Description

Regression: Tested in UE5/Release-5.0, this issue does not occur so it is a regression

Appears to be an issue with Lumen and Skylights with Cubemaps. Directional lights, point lights, etc. all work properly with translucent materials.

Steps to Reproduce
  1. Create a new Blank project with an Empty level
  2. Create a new material
  3. Set the material to be Translucent
  4. Assign the Base color to a Constant Vector 3 of 1,1,1 
  5. Add a Skylight to the scene
  6. Set Source Type for the skylight to SLS Specified Cubemap
  7. Set the Cubemap to any cubemap (tested using "daylight")
  8. Add two spheres to the scene
  9. Assign the translucent material to one sphere

Actual Result: Sphere with the material renders completely black instead of receiving light from the Skylight and Cubemap.

Expected Result: Translucent sphere should render visible due to the light from the Skylight and Cubemap
