RT shadows break with a 16-bit GBuffer

RT shadows break with a 16-bit GBuffer

Description

Ray traced shadows are missing when the gbuffer is forced to 16-bit.

Steps to Reproduce

In QAGame, in Project Settings:

  • Set "GBuffer Format" to "Force 16 Bits per Channel"
  • Enable "Ray Traced Shadows"
    Restart the editor if needed.

Open TM-Shadows-RayTracing, observe that shadows are broken.
Resetting "GBuffer Format" to "Default" restores the shadows.
