Preparation

Follow the initial steps from 1.4 | Setting up a VS level:

  1. Create a new project

  2. Make sure you are working in Video space (Director: SETUP → Configure → Video I/O → Compositing color space)

  3. Launch level
  4. Go to Editor
  5. Create new empty level
  6. Create a virtual scene
  7. Add or import your 3D assets

XR set extension

If you plan an additional XR set extension, separate the graphics and XR content using a level streaming setup.

Add XR wall

Add XR wall actors for all real world screens.

  1. Add an "XR wall" to the level which can be found in Place Actors → Pixotope
  2. Position and scale the XR wall to align with the real world LED walls

    • Enable WYSIWYG to make aligning the walls easier

      Learn more about WYSIWYG and the Edit mode in general.

Choose output position

  1. Select the XR wall and go to the "XR" section in the "Details" panel
  2. Set “Output Position” to how the rendering of this XR wall should be output. These are the options:
    • Full screen
    • One of the four corners
    • Custom - specify exactly where to output to (location available as CustomOutputPositionMin and CustomOutputPositionMax)

Enable XR rendering

  • Go to the "Pixotope XR Compositing" section in the "World Settings"
  • Enable "Output XR to SDI"

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"

Advanced settings
