Enhanced 3D Display with Unreal Engine

2022.1 and Newer

The integration of the Unreal engine enables very fast ray trace rendering and an improved 3D display that displays high quality shadows and reflections in real time.

The following image shows the difference in the 3D display with ray trace and without.

Real- Time Ray Trace Rendering with Unreal

The integrated Unreal engine allows fast, high quality ray trace rendering. The Real-time ray trace checkbox is enabled by default for users with a graphics card from Nvidia with RTX support. Real time ray trace rendering option is disabled for users without a graphics card from Nvidia with RTX support. For more information, refer to the Hardware for real-time rendering section at the bottom of the page.

To do ray trace rendering with Unreal:

1. Open Lotta.

2. Open VStitcher.

3. On the Main menu, click:

   • Edit (Windows)

   • Lotta (Mac)

   • VStitcher (Mac)

6. VStitcher 2022.1.5 and newer

   Select which 3D display engine to use for rendering (Unreal/OpenGL).

   Note that Open GL does not support real time ray trace rendering. When you switch to the Open GL option, the Real time ray trace rendering option is disabled.

7. Check the Real time ray trace rendering box, then click OK. (Optional)

8. Toggle the Enable Displacement in production render checkbox to use displacement. V-ray render does not show displacement, the Enable Displacement in production render option will be disabled.

9. Restart VStitcher.
