Pixotope XR tools are currently in Experimental stage.

Preparation

Follow the initial steps from 1.5 | 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 physical 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 physical LED walls

    • Enable WYSIWYG to make aligning the walls easier

      Learn more about WYSIWYG and the Edit mode in general.

Academy Tutorial - XR Manual Alignment

  • Learn how to align the XR walls in Pixotope with the physical LED wall


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".

When using virtual camera moves, make sure to enable "XR From Current Camera" in World Settings > Pixotope XR Compositing.

Advanced settings

World settings → Pixotope XR Compositing

Disable TonemapperChecked by default as one usually does not want tonemapping on XR Walls.
(The tonemapping is handled by the display gamma of the output device)
XR OverscanBlends between inside and outside camera view - 1 is no blend
Automatically Optimize Camera Rotation and FOVPixotope 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

Enhanced rendering

Changes the rendering pipeline to ensure higher quality. It enhances the rendering of the tonemapper and other effects.

NOTE: This option shows the projected XR output on the viewport. We therefore recommend enabling it after you have set up your XR level, before you go live.

Update Frequency Of Outside Camera View1 is every frame, 5 is update disabled
Use Only Outside Camera View Renderingfor debug use
Sample Outside Frustum ColorReplacement color for the outside rendering pixels (can be set if "Render Outside Camera View" is disabled)
XR supersampling (NVIDIA DLSS 2.0)Uses NVIDIA's DLSS 2.0 to increase the quality of the XR rendering. For supported graphics cards and more details see 1.5 | Using NVIDIA DLSS

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.

Previous implementation with Off Axis plugin

How to use the Pixotope Off Axis plugin
  1. Enable the plugin
    1. Open the "Plugins" window via Edit → Plugins in the window menu
    2. Click on the "Pixotope" category and enable "Pixotope Off Axis"
    3. Restart the Editor
  2. Add a Pixotope Off Axis Window from the Place Actors panel → Pixotope
  3. Place and scale the window where you want your virtual window to be
  4. Set the Local Player Class to "OffAxisLocalPlayer" in Project Settings → Engine - General Settings → Default Classes - Local Player Class
  5. Save and restart the Editor

If your camera system uses a lens file, disable lens distortion in Director → Configure → Tracking → Lens Tracking → Advanced → Disable Distortion
