Description

Ray Traced Translucency Option Doesn't Work in Post Process Volume.

Found in 4.23 Preview 6 CL# 7848402, and 4.24 CL# 8074192

Working as expected in 4.22 CL# 7053642

This is a regression.

Steps to Reproduce
  1. Open the Editor in DX12
  2. Enable Ray Tracing
  3. Create a translucent Material
  4. Place a Post Process Volume in the scene and enable infinite extent
  5. Place any mesh in the scene and apply the material
  6. Set "Translucency" to Ray Tracing

Results:
Translucency will remain as Raster

Expected:
Ray Traced Translucency would be enabled

Note:
The CVar r.RayTracing.Translucency will still enable or disable RT Translucency properly
