Study Modes
The 3D Viewer panel has two different rendering modes : Study mode and Rendered mode.
You can read more details about the differences between these two modes, and particularly the characteristics of the Study mode in the dedicated manual page.
When in Study mode, each viewport can be configured to display projection study information.
Luminosity mode
While in the preset Front POV previously created, add another preset in the 3D Viewer panel.
When creating a new preset, the previous preset is duplicated and the newly created preset is inserted immediately to it’s right.
Use the MOUSE WHEEL to zoom out from the camera view.
When zooming out from a camera or projector point of view, the viewport automatically switches back to the default camera in perspective mode starting from the same point of view and you are free to move the camera around again.
Rename this preset Free Camera and set a viewpoint where the castle is centered and fully occupies the viewport.
Click on the 
icon in the top right of the viewport.
In the Editor panel, set Projection Mode to Luminosity.
This mode shows the calculated lux values of the projection depending on projector power.
Adjust the min and max values so as to have the full gradient displayed on your structure.
Select both projectors in the Hierarchy tab of the 3D Scenes panel.
Change their Lumens value to 30 000.
Go back into the Viewport’s options with the icon and re-adjust the min and max values.
Pixel density and Size
There are other display modes available when in Study Mode.
In the Editor panel, set the Projection Mode to Pixel density.
Adjust the min and max values so as to have the full gradient displayed on your structure.
The pixel density displays the quantity of pixels per square meters of the projection.
Set the Projection Mode to Horizontal pixel size.
Adjust the min and max values again.
This mode displays the horizontal size of the pixels in the projection on different parts of the structure.
Projector adjustment
Select both projectors and in the Editor panel, enable the Show beam option.
Notice that the bottom of the projection is beneath the bottom of the castle.
Adjust the view to see more clearly and with both projectors selected, adjust the Horizontal Shift value to align the bottom of the projection with the bottom of the castle.
Disable the Show beam option and with one projector selected, enable the Projector info by clicking on the 
button in the 3D Viewer panel
Note that you can
CLICKandDRAGthe center point of the projection to snap it to a part of the mesh.
Study vs Rendered Mode
Switch between the first preset Front POV and the second preset Free Camera.
Notice that the study mode displays we have set are viewport dependant and can be set independently on every viewport.
Select the preset Free Camera and switch between Study Mode and Rendered Mode.
Notice that the study mode displays are only available when in Study Mode.
Open the 3D Scene settings by clicking on the 
next to the 3D Scene name in the 3D Scenes panel.
Adjust the value of the Env. Map intensity property and observe the results in the 3D Viewer.
Notice that the towers we created go black when the Env. Map intensity is at 0, but not the castle.
Adjust the value of the Env. Map opacity property to visualize the environment map that lights the scene.
Open the Materials tab of the 3D Scenes panel and select the Castle Texture material.
Because this is an Unlit material it does not react to lighting and will always display at 100% brightness.
Select the default PBR Material to compare the properties of a PBR Material and an Unlit material.
