With XR you can extend your physical set beyond its borders or create a virtual window into another world. This is done by rendering the virtual scene onto for example LED screens using the perspective of the camera.
The XR Wall is a special Pixotope actor which is used as the representation of the physical display screen within the virtual environment.
Settings in Engine/Editor
Per XR Wall
Choose how to place this XR Wall on the render output. Options are
The index of the Output routed to this machine, onto which the XR Wall should be rendered to.
Custom Output Position Min/Max
When the Output position is set to "Custom", use these parameters to specify the exact position of the XR Wall on the render output.
Compensate for color discrepancies of the physical planes.
World settings > Pixotope XR Compositing
This enables XR rendering
Experimental feature to help with position/rotation calibration of XR walls
Default internal buffers for XR walls if no output is routed to the machine
Checked by default as one usually does not want tone mapping on XR Walls.
Blends between inside and outside camera view - 1 is no blend
Automatically Optimize Camera Rotation and FOV
Pixotope will take control of the virtual camera to optimize the view for the output
Render Outside Camera View
Renders an environment quality version of the areas of the scene which are outside the camera's view (frustum)
NOTE: Disabled when "Automatically Optimize Camera Rotation and FOV" is enabled
Update Frequency Of Outside Camera View
1 is every frame, 5 is update disabled
Use Only Outside Camera View Rendering
for debug use
Sample Outside Frustum Color
Replacement color for the outside rendering pixels (can be set if "Render Outside Camera View" is disabled)
XR From Current Camera
Uses the current camera position to project XR. Enable this when using virtual camera moves.
Disable Custom Depth
Gain performance by disabling Custom Depth rendering (disables AR and VS)
Disable Motion blur in XR
Disables motion blur in the render output. Checked by default.
