For functionality specific to the Unreal Editor and some in-depth knowledge, check out https://docs.unrealengine.com/en-us/Engine/Editor.
Follow the initial steps from Set up a VS level:
Create a new show
Make sure you are working in Video space
In Director check: SETUP > Show > Show settings > Compositing color space
Launch the level
Go to the Editor
Create a new empty level
Create a virtual scene
Add or import your 3D assets
Virtual set extension
If you plan an additional virtual set extension, separate the graphics and XR content using a level streaming setup.

Add XR wall
Add XR wall actors for all real world LED screens.
Add an "XR wall" to the level from Place Actors > Pixotope
Position and scale the XR wall to align with the real world LED walls
Enable WYSIWYG to make aligning the walls easier
Academy Tutorial - XR Manual Alignment
Learn how to align the XR walls in Pixotope with the physical LED wall
Convert pre-made meshes to XR walls
Often aligning the 3D XR wall with the physical LED wall is difficult. Our creative engineers have created a tool that allows you to convert any mesh, or multiple meshes, into XRWall actor(s). Technically we create an XR wall for each mesh quad.
If your mesh is properly measured to represent your physical LED setup (from a CAD drawing or .obj file for example), the setup should only take minutes.
Import mesh(es) into your level
Right click the selection
Select “Generate XR walls from Actors”
Use the following menu to fine-tune the generation
if your XR walls are facing the wrong way, toggle “Flip Normals”
“Optimize Faces” will collapse faces that share vertices and have a similar normal direction. See the following gif for an example
“Optimize Threshold” is for the normals' value. By default this value is almost touching, but can be manipulated if the normals are at all shifted
Choose output position
Go to the "XR wall settings" tab in PRODUCTION > Adjust > XR
Select the XR wall
Set the "Output position"
OR from Editor
Select the XR wall
G to the "XR" section in the "Details" panel
Set the "Output Position"
Enable XR rendering
Go to the "General" tab in PRODUCTION > Adjust > XR
Enable "Output XR"
OR from Editor
Go to the "Pixotope XR Compositing" section in the "World Settings"
Enable "Enable XR"
To output the XR wall texture(s) also in the viewport and the computer monitor when in live mode, change the "Visualization Mode" in World Settings > Pixotope World from "Normal" to "Off-axis texture".
When using virtual camera moves, make sure to enable "XR From Current Camera" in World Settings > Pixotope XR Compositing.
To increase image quality using NVIDIA's DLSS go to PRODUCTION > Adjust > Effects > Image up/down sampling.
