Modeling Concepts for LightStanza

This guide is meant to help you organize your 3D models and streamline your workflow to make it easy to work with your product later. In order to ensure an efficient and organized modeling process, you will also need to be familiar with how to build your model flexibly with materials and layers.

We recommend organizing your model by layer or material to allow for more flexibility later in For example, you will have windows in your project, but they may not all perform the same function. In the illustration below, there is a row of windows with an accompanying row of daylight windows. The bottom windows will be standard, but you want the daylight windows to have a special type of daylight glazing. Putting the daylight windows on their own layer will make it easy to assign each window type its specific properties.


One way to organize your model is through material assignment. Material assignments should be used when you want to change the lighting characteristics of a polygon. For example, you can change something from glass to opaque or vice versa, convert a polygon to a BSDF file, convert to a translucent plastic, etc.

Each part of the model that will have different light behavior should be a unique material. Initial settings are taken into account during the upload process (materials with less than 100% opacity are assumed to be glass), but it does not matter which material you assign when you are working in SketchUp since everything can and should be changed later on See the illustrations below for details.

* Note on SketchUp Textures: LightStanza initially analyzes materials based on RGB values and opacity. SketchUp Textures are not supported by LightStanza since they are not physically accurate descriptions of materials (like .bsdf files are). If you have SketchUp Textures in your model, be sure to assign a different material either in SketchUp or on

If you are using Revit, your glass and opaque materials will go through a conversion when uploaded to LightStanza. Below are the conversion formats for the two material types:

  • Glass Materials: LightStanza reads the red, green, and blue transmission values (tr, tg, tb) directly from the Revit material, and converts them to a simple VT value (note that the tr, tg, and tb values are passed directly to Radiance): T = tr * 0.2126 + tg * 0.7152 + tb * 0.0722 VT = (100 * 0.5 * (-√(2.45 × 10104 * T2) + 6.57 × 1097) – 1.57 × 1052 * T) / (3.10 × 1049 * T2 – 1.71 × 1052)
  • Opaque Materials: LightStanza reads the red, green, and blue reflectance values (R, G, B) directly from the Revit material, and converts them to a simple, combined reflectance value: Reflectance = 100 * (R * 0.2126 + G * 0.7152 + B * 0.0722)


Another strategy you should use for model organization is layers. Layers should be used to organize and control geometry. Things like furniture, window blinds, and overhangs will typically be on their own layers. When furniture is all on a separate “Furniture” layer, you can turn the layer on and off on This is useful because it is interesting to see the furniture in renderings, but it should be turned off if you are only interested in getting quick quantitative results.

* In SketchUp, if you have any “components” in your model, you must “explode” them before saving your model in order for layers to be assigned correctly after uploading your model to LightStanza.

* Please note, layers are created as “layers” in SketchUp, “categories” in Revit, and “layers” in Rhino (Rhino layers are also imported to LightStanza as materials). More information on layers in Rhino coming soon.

Layers and Materials, Illustrated

The next three illustrations show how to use layers and materials.

Elevation A Shows a set of daylight windows with daylight film and a set of view windows. In this elevation we see three unique materials. The facade is assigned material “Wall”, the windows with daylight film are assigned material “Daylight Window”, and the view windows are assigned material “View Window”. Name the materials something that you can easily identify on when you assign them specific properties.

Elevation A

In Elevation B we see two layers and two materials. The facade and windows represent Layer 1, and the overhang is Layer 2. The facade and overhang are the material “wall” and the windows are material “View Window”. The overhang should be modeled on its own layer, which can be turned on or off on That way, you will be able to see how the room is lit with and without the overhang and assess its effectiveness. You can also add other overhang layers to account for vertical fins and turn them on individually or in conjunction with the horizontal overhang layer.

Elevation B

In Elevation C there are two layers and three materials. There is one set of daylight windows with daylight film and an overhang. The two sets of windows will have different material properties assigned to them.

Elevation C

You can also assign material properties to the glazing and blinds or shades, as well as define the covering (blind/shade) behavior after you upload your model to

Modeling the Ground Plane

It is essential to always model your ground plane. Without modeling a ground plane, your simulations will not accurately depict light bouncing from the ground into your space. Below are ground plane guidelines to follow.

Wall Thickness and Detail

The thickness of walls in buildings affects the way light enters the space. For accuracy in light analysis as required by LEED and WELL standards, construct your SketchUp model with accurate wall thickness, but windows as only a single pane. You will assign all complex lighting functions and characteristics for the window on Multi-plane glass, blinds, and daylight film are all examples of complex lighting functions that you will assign on For example, even if the window will be triple-pane glass, model it in SketchUp as single plane.

SketchUp Model
Rendered Model (by LightStanza)

Modeling wall thickness and other fenestration details like mullions increase realism in images and accuracy in calculations. Note the two different glass materials in the SketchUp model allow for flexible and independent assignment of the daylight and view window properties.

This is an example of how details like wall thickness have significant impacts on daylight quality.

Model Units/Scale

Make sure to double check the units (e.g. sizes/lengths) within your model before uploading. This will ensure that the model is scaled correctly. If the model is not scaled properly in your modeling software (i.e. too big/small), daylighting results may be incorrect.


Floors in LightStanza are for display purposes only and do not impact simulation results. They are intended merely as a convenience for organizing and viewing data. Floors are generated automatically and currently cannot be changed after they are created. Please note that the floor assignments when viewing grids in the Illuminance Grids Panel and when viewing simulation results may not always correspond exactly.

The floors displayed in the Illuminance Grids panel are assigned based on grid height and take both user-defined and automatically-generated grids into account. Grids are sorted by height, and the lowest grid is assigned to Floor 1. The next-highest grid is then checked, and if its height is within 1m of the first grid on Floor 1, this grid is also assigned to Floor 1. Otherwise, a new floor (Floor 2) is created to which the grid is assigned. This process is repeated until all grids have been assigned to a floor.

The floors displayed on a simulation report only take grids that are active for that simulation into account. During simulation, groups of coplanar grids are created and then sorted by the height of the center point of the group to create floors. If grids are coplanar but point in opposite directions (e.g. some face upward while others face downward), they will be assigned to separate floors. Grids that are not horizontal (e.g. grids measuring vertical illuminance on a wall) will be assigned to floors named e.g. “Section 1”, “Section 2”, etc.

Preparing your Model for Generating Results in LightStanza

This section will teach you how to use your 3D modeling tool to prepare for generating results in LightStanza. Then it will explain how to kick off simulations from the activity bar using the left toolbar simulation settings.

Current Caveats of Different 3D Modeling Software

  1. To ensure model translation accuracy, uploading Revit and SketchUp files requires the use of our free LightStanza Plugins. For SketchUp models, you can also first export in Collada format and then drag-and-drop into LightStanza.
  2. There are different steps for manually uploading illuminance grids from SketchUp, Revit, and Rhino. To learn these different workflows, visit the Create an Illuminance Grid section below.
  3. There are different steps for uploading windows from SketchUp, Revit, and Rhino. To learn these different workflows, visit the Create Windows section below.
  4. LightStanza does not support different materials applied to the front and back sides of SketchUp objects. For best performance, apply the same material to both sides of an object.
  5. Rhino materials are not uploaded to LightStanza. Instead, materials are differentiated display color or layer name. Glass materials have a blue display color (or be on a layer with “glass”, “window” or “glazing” in the name), and opaque materials may be any other color. For more details see Create Windows In Rhino.
  6. LightStanza does not currently support importing textures from external modeling software. Materials with textures applied will have these textures removed when importing into LightStanza.

How to Create an Illuminance Grid

An Illuminance Grid is a planar system of points that collects light for analysis in your model. These can be horizontal or vertical. To create an Illuminance Grid in your modeling program, you can name a material “LSGrid” (SketchUp), use the LightStanza plugin (Revit), or change the color of a material to yellow (Rhino). Below are detailed instructions for each modeling program.

Please note that LightStanza automatically creates Illuminance grids when you upload your 3D model. These will be placed 30 inches (762 mm) above the floor. You still have the option to manually create user-defined illuminance grids, which are helpful for precise separation of spaces and for measuring light vertically.

Above is Illuminance Grid output in the LightStanza 3D viewer. In this section, you will learn how to generate results like these.
In Revit
There are multiple ways to make illuminance grids in Revit. Each method is broken down below:
LightStanza Plugin for Revit

Allows you to transform your Revit rooms into LightStanza illuminance grids (required for LEED credit). Here’s how to use it:

    1. Download the LightStanza plugin for Revit, and follow the download instructions provided by the Autodesk App Store.
    2. Make Revit rooms that you would like to be tagged as illuminance grids in LightStanza. To learn how to create rooms in Revit, click here.
    3. If your model has any linked files, LightStanza should be able to read the files without having to bind them. To learn how to work with linked files, click here.
    4. Once you have made a room to represent each illuminance grid, make sure you are in the default “{3D}” view.
    5. Make sure your model is in the correct project phase before bringing it into LightStanza. For more information on project phases, click here.
    6. Click the “Export to LightStanza” button on the LightStanza plugin for Revit.
    7. A popup will appear before your model exports, where you can choose export settings.
      1. Automatically remove all furniture from your model: If this is checked, LightStanza will automatically remove furniture from your model that is not necessary for daylight analysis. This will improve the performance of your model during export and inside of LightStanza.
      2. Choose a height for your illuminance grids: Here you can choose between United States and European standards for workplane height, which is the distance your illuminance grids are from the floor.

    8. If any of your rooms do not translate to illuminance grids, you will get a warning message that includes the names of problematic rooms. If you get this warning, you can click “Cancel” to ignore those rooms and export to LightStanza without them, or see the workarounds section.
    9. If your model has linked files, you will get a warning message because LightStanza will only upload what is in the main file, and not what is linked. You will need to remove the links or bind them into a single .rvt file in order to avoid errors. To learn how to work with linked files, click here.
    10. Then you will be required to enter your LightStanza username and password.
    11. When export is complete, your model will automatically open in LightStanza, where you can begin simulating results. Your Revit rooms will automatically be listed as illuminance grids in the left Illuminance Grids panel in LightStanza, where you can turn them on, off, flip them, rename them, and measure annual and point-in-time illuminance from them.
Saving a LightStanza File (.lsd) in Revit to Hand off to another LightStanza User
  1. Choose “Save to disk” on the Ribbon of the LightStanza tab in Revit

2. Adjust model parameters using the LightStanza Plugin

  1. Name your LightStanza model
  2. Click the lightbulb to include or exclude fixture families from your Revit model when uploading into LightStanza
  3. Choose to export the entire model or individual levels or rooms
  4. Not adjustable
  5. Choose the Revit families to export into the LightStanza model
  6. Illuminance grids will be created based on Rooms or Spaces defined in the Revit model
  7. Designate the workplane height for illuminance grids or adjust in the app
  8. Select to create vertical illuminance grids

3. Save the .lsd file to your computer drive

4. Navigate to the LightStanza online app and create a “New Design”

5. In the New Design, click the “+” and select “Choose file”. Navigate to the file location on your computer and upload the .lsd

It is also possible to drag and drop the .lsd file into the LightStanza interface

6. Your Revit model will upload into the LightStanza app

 Workarounds to the LightStanza Plugin for Revit are listed below:
  1. Some Rooms Are Not Converted Into Illuminance Grids: Please note that sometimes special characters (e.g. square brackets) in room names can prevent them from being converted into illuminance grids. If you receive a warning about rooms not being converted properly, but do not see any room names listed, this is likely the case and you should check your room schedule and adjust names as needed.Revit occasionally defines the boundries of rooms in ways that prevent them from being properly converted into illuminance grids. One common case is to have distinct spaces that are part of the same room, as shown below (the highlighted areas show a “single” room): In this situation, you should split this space into two rooms (or one, if part of the space Revit defined is not desired). To do this, click on the “Architecture” tab at the top, and find the “Room & Area” section: Use the “Room Separator” tool to draw lines that split the main room off from the second piece. If you would also like the separate piece to receive an illuminance grid, you can use the “Tag Room” tool to create another room for it. If there are additional rooms that are not converted to illuminance grids, you may have to create grids for these spaces manually. Once these are defined, you can export with the plugin as usual — grids that are both manually-defined and defined by rooms will be recognized by LightStanza.
  2. Automatic Full-Floor Grids: LightStanza will automatically generate illuminance grids based on a Revit model’s “Floor” objects. Each floor object will have an illuminance grid placed on top, raised to the workplane height. To upload space-by-space illuminance grids (needed for LEED v4), just separate out the floors in your model into individual spaces (this would result in multiple floors on one level to indicate different spaces).
 Creating a Vertical or Custom Grid in Revit:
  1. Create a new material in Revit by going to the Manage tab, then clicking on Materials.
  2. Next, click the gray circle with a plus on it which is located at the bottom of the materials list and then click “Create New Material”.
  3. Once the material is made, change the “shading” and the “surface pattern” colors to yellow RGB(255,255,0) and then the “surface pattern” to “” on the right panel.
  4. Click on the Appearance tab and change the generic color to yellow as well. Make sure there is no image selected as well.
  5. Rename the new material to “LSGrid” + whatever you want the grid name to be in LightStanza (i.e. “LSGrid Grid 1”) by right clicking it in the “Project Materials” list, and clicking “Rename”. Then click OK.
  6. If you are creating a horizontal grid, create a new “level” by going to an elevation view. For a vertical grid, use the floor plan view where you want to make the grid.
  7. Make sure you are not in Modify mode for this step. Click on a level and then type “cs” for the keyboard shortcut to “create similar” this will create a new level. Set the new level to 30” above the actual floor for workplane measurements.
  8. Next, go to your newly created level by clicking on its floor plan view.
  9. Next, create a new floor or wall by going to the architecture tab and clicking on floor or wall. Under the properties section on the left, click “Edit Type”. This will bring up a new menu.
  10. To create a new type of floor or wall click “duplicate’ and give the object a new name. Click OK.
  11. Now click on “edit” to the right of the structure parameter.
  12. Set the structure of this object/grid to just one layer and set that layer material to the one you created in step 1. Make sure to set the layer to as thin as possible (the minimum thickness in Revit is 31/256″). This will essentially make the object a 2D plane in Revit (0 thickness). Click OK, and then OK again on the Type Properties Menu.
  13. Make sure the type is set to the grid floor that you created in the left properties tab.
  14. Draw the floor (which will upload as your illuminance grid in LightStanza) in any shape you want using the drawing tools. If you would like to separate out your illuminance grids into spaces, draw multiple shapes to represent each of your spaces. When you are done, click the green checkmark.
  15. Next, upload your model to LightStanza. You can either save your model as a .rvt file and upload directly to LightStanza, upload through the LightStanza Plugin for Revit, or upload through the Legacy LSGrid Plugin for Revit. * On LightStanza that the object will turn into an illuminance grid and will no longer be the object that it was in Revit so it will not interfere with your lighting calculations.
In SketchUp
    1. Draw a polygon where you want your Illuminance Grid to be. A helpful tip is to make a copy of the floor and move it up to workplane height (30″ or 760mm above the floor), or to the height at which you wish to measure light. Illuminance grids can be standard horizontal, vertical, or diagonal.
    2. Choose the planes in your model that you would like to measure daylight on and rename the corresponding material to include the text “LSGrid” (this is not case sensitive).* It is recommended that you assign the grid material to both sides of the polygon. Assigning only the back face material will not create an Illuminance Grid in SketchUp if the front face is not also assigned.
      1. For example, if your material is “Office 323” and you rename it to “LSGrid Office 323”, the polygon will be added to your list of grids. Additional text beyond “LSGrid” will be used as its name online, such as naming ‘Office 323’ and ‘Office 345’ the following material names can be used:
        1. LSGrid Office 323
        2. lsGRID Office 345
        3. LSGrid Kitchen
This screenshot shows “LSGrid Workplane” added to a material name in SketchUp 2018 for Windows. After saving this model and uploading it to LightStanza, the polygon with this material will appear in the “Illuminance Grids” panel for you to begin measuring light.
This screenshot shows “LSGrid” added to a material name in SketchUp 2017 for Mac. Both horizontal and vertical polygons will work as illuminance grids with “LSGrid” added to the material name.
  1. Once the desired materials have been renamed, save your model by clicking “save As” > “SketchUp (*.skp)”.
  2. Export your model to LightStanza using the LightStanza Extension. If you are unable to use extensions with your version of SketchUp, first export it as a Collada file (File -> Export -> 3D model) and then drag-and-drop the .dae file or use the “+” button in the top menu.
In Rhino
  1. Draw a planar surface where you want your Illuminance Grid to be. A helpful tip is to make a copy of the floor and move it up to workplane height (30″ or 760mm above the floor), or to the height at which you wish to measure light.
    1. Illuminance grids can be standard horizontal, vertical, or diagonal.
  2. Choose the planar surfaces in your model that you would like to measure daylight on and put them on a new layer. Change the color of this new layer to yellow; which is RGB(255,255,0).
  3. Save your model and upload it to a LightStanza design. The illuminance grids you made will appear under User-Defined Grids inside of the Illuminance Grids tab in the left toolbar.
Creating New Grids in LightStanza

Click the “+” symbol under the “User-Defined Grids” tab on the Illuminance Grid panel. Click anywhere in the 3D or 2D model to place the illuminance grid.

Adjust the size of the illuminance grid, its orientation as well as it’s height in either the 2D or 3D LightStanza mode.

Adjust the room type and target illuminance value for each new grid that is created.

All grids are adjustable in either 2D or 3D

Automatic Grids

LightStanza will automatically generate illuminance grids for SketchUp or Rhino models that are imported into the app. 

The automatic grids are accessed on the Illuminance Grids panel within the LightStanza app.

Using LightStanza on an iPad

If you are using LightStanza on an iPad, make sure to “Request Desktop Site” for easier-to-use 3D controls. You can do this in both Safari and Google Chrome:

  1. Using Safari, hold your finger/cursor down on the “Refresh” button next to the address bar. The option to “Request Desktop Site” will pop up below for you to click on.

  2. Using Google Chrome, click on the top right menu button and select “Request Desktop Site” from the dropdown menu options.

Editing your Model in LightStanza

This section will cover the different elements of the left toolbar in the LightStanza 3D viewer. Making changes in this panel will affect your model settings. Model settings have to do with the physical components of the 3D model.


Viewpoints List – In the Viewpoints tab, there may be a list of viewpoints that were uploaded from your CAD tool. You can also create new viewpoints in LightStanza by navigating the 3D viewer to the desired location and angle and clicking the ‘+’ sign next to Viewpoints. Clicking on the viewpoints in the list will move you to the corresponding camera location and angle in the 3D viewer. These are not necessary to make renderings (renderings can be made in LightStanza from on-the-fly viewpoints. In other words, if you start a new rendering, it basically takes a snapshot at the current location and angle of your 3D viewer).

Illuminance Grids

Illuminance Grids List – Your Illuminance Grids tab is split into three sections: Favorite Grids, User-defined Grids, and Automatic Grids. User-defined Grids are a list of illuminance grids that were assigned in your 3D modeling program. To learn how to populate this list, see the Illuminance Grids Section above. Automatic grids are automatically added to your model when you upload it to LightStanza. LightStanza does its best to put these at the workplane on each floor of your model, but if you need space-by-space or custom grid measurements, it is best to create them in your 3D modeling tool (explained in the Illuminance Grids section above). Favorite Grids are those you mark with the “Star” icon. This tool is great creating scenes of grids for reference. You can do a few things with the grids listed on this panel:

  1. Hovering over individual grids will highlight them in the 3D viewer for reference.
  2. Selecting and deselecting the check-boxes on each illuminance grid will turn them on and off for viewing and for simulations (for example, if you would like to exclude unoccupied spaces from your LEED v4 Daylight Credit Report, deselect those spaces in the Illuminance Grids tab so that they will not be included in the calculation).
  3. Clicking the “Flip Grid” button (click the pencil icon to view) next to each grid will change the side that light is measured on. Here is how to do this:
    1. First you will need to determine the direction your Illuminance Grids are facing. In the LightStanza 3D viewer, locate the illuminance grids in your model. The orange side of the illuminance grid is the side that will measure light. The black and yellow striped side will not measure light.
    2. If any of your Illuminance Grids are facing the wrong direction (i.e. the orange side of the polygon is not facing the side you want to measure light on), you will need to flip them in LightStanza. To do this, find the grid that needs flipped in the left toolbar Illuminance Grids panel. When hovering over the individual grids, you will see a pencil icon. Click it for access to the “Flip Grid” icon. Click this icon and it will change which side of your Illuminance Grid daylight gets measured on.
  4. The light bulb icon associates a recommended light level from the IES handbook with the specific space. If importing a model from Revit, LightStanza will attribute a “Room Type” to that grid based on the Room name in the model. This “Room Type” will generate a target illuminance level per the IES recommended values as well as allow for definition of that level as an average, max or min value. 
  5. The “Crop to Space” button allows you to reduce the model to that specific illuminance grid. 
  6. Under “User-Defined Grids” or “Favorite Grids” you can create new illuminance grids in the LightStanza model. These grids may be adjusted in the same ways as those that were automatically defined in the model. 


The Materials panel allows you to edit the materials in your model, along with their properties. This panel is separated into three categories – materials that are in your design, manufactured products (Product Library), and the generic materials.
    1.  In Design – This list will show the materials that are in your design. From here, you can edit properties, select all, apply materials in your 3D model using the paint bucket tool, delete unwanted materials from your design, and save materials to your material library.
        • Edit Properties – You can edit properties of your materials in two different formats – simple or “Radiance Format”. To turn Radiance Format on, click “View” at the top right of the material toolbar, and then click “Radiance Format”. Repeat this step to go back to simple mode. Each mode has different customizable properties.
        • Please note that Dynamic Glass does not have editable properties since it has multiple tint states. Below is a list of these tint states.
        1. 3-tint:
            1. <15,000 lx: 0.6VT
            2. 15,000 lx – 50,000 lx: 0.15VT
            3. >50,000 lx: 0.01VT
            1. <15,000 lx: 0.58VT
            2. 15,000 lx – 30,000 lx: 0.4VT
            3. 30,000 lx – 50,000 lx: 0.06VT
            4. >50,000 lx: 0.01VT
      * These are the illuminance levels measured at the center of each window group with dynamic glass.

    2.  Product Library – This is a list of manufactured products separated by manufacturer name. To use these in your design, click on the desired product and it will be moved into the “In Design” library where you can use the paint bucket to apply it to polygons in your model. Information about modeling skylights can be found here, and information about modeling tubular daylight devices can be found here.

    3. Generic Materials – This is a list of generic materials. To edit or use these in your model, simply click on a material, and it will move into the “In Design” library where you can use the paint bucket to apply it to polygons in your model.
This section will teach you how to navigate the 3D viewer in LightStanza. The controls mentioned here are in the top toolbar. Buttons and references will hide and show depending on the type of data that is showing in the 3D viewer.

    3. Look South – Clicking this button will adjust the camera to be looking in the South direction.
    4. Look West – Clicking this button will adjust the camera to be looking in the West direction.
    5. Look Up – Clicking this button will adjust the camera to be looking directly up.
    6. Look Down – Clicking this button will adjust the camera to be looking directly down.
  1. Wireframe Mode – When clicking this button, you are able to make all opaque surfaces clear in your 3D model. This allows you to clearly view your results in the 3D viewer without any polygons in the way.
  2. Show/Hide World Elements – Click this button to show/hide elements in the viewer that are not part of the model (the sky, ground, Sun Path, and compass rose). This is particularly useful when taking screenshots for reports and presentations.
  3. Section Cut – By clicking this icon you can cut into your model to view results more easily. When you click the “Section Cut” icon, you can adjust the cut location using the text input box to the right. You can also change where the section cut begins (ground or camera). Ground is the default, but can be changed by selecting ground to the right of the text input box.
  4. Show/Hide Sensors – These two options allow you to turn sensors for dymanic glass and blinds as well as illuminance sensors on/off. The amount of daylight that hits these sensors controls the way the blinds and dynamic glass operate.
  1. Animate Results – Animation controls include play, stop, back, next, and the date/time for reference. These will only appear when an animation is open in the 3D viewer.
  2. Date/Time – When renderings or point-in-time illuminance grids are in the 3D viewer, there should always be a date and time for reference in the top toolbar. This is the date and time that the rendering or illuminance grid data represents. When viewing LEED v4 Option 2 or LEED 2009 results in the 3D viewer, this is section will either say 09:00 AM or 03:00 PM.
  1. Average/Compliance/Annual Score – When Point-in-time Illuminance Grids, Annual Illuminance Grids, or LEED Scorecard results are in the 3D viewer, this section will show a value and a corresponding legend. These numbers represent all of the grids that are currently showing data in the 3D viewer.
  1. Rendering Controls – When opening a rendering, a new set of rendering-specific elements are added to the top toolbar:
    1. Daylight Glare Probability (DGP) – This reference will only appear when you have opened a hemispheric rendering. This percentage represents the probability that a person is disturbed by glare at this specific viewpoint.
    2. Camera Tools – These three buttons allow you to switch between basic rendering mode, false color mode, and contour lines mode. The rightmost slider controls will change depending on which mode you are in.
      1. Exposure – You can manually adjust the exposure of your renderings in order to increase or decrease the amount of light per unit area. LightStanza uses Reinhard tone mapping for adjusting exposure.
      2. Contrast – Adjusting the contrast of your image will increase or decrease the difference between light and dark in your renderings.
      3. False Color – In the 3D viewer, you have the option to view your renderings in False Color mode for a more quantitative view of your images.
        1. Luminance Bounds – Changing your luminance sets what luminance values each color in your image represents. Adjust this to focus on very bright or very dark areas.
        2. Log Scale – Adjusting your log scale sets scaling of your false color heat map.
      4. Contour Lines – This is another way to look at your false color rendering. Contour lines trace the different luminance thresholds in your rendering, using the false color legend.
        1. Line Spacing – Changing your line spacing sets the density of the contour lines in your image.
