Crash While Running Project With d3ddebug Enabled (fix provided)

Crash While Running Project With d3ddebug Enabled (fix provided)

UDN
Description

A licensee encountered a crash during InjectTranslucentLightArray: according to them they fixed the issue in ShadowProjectionCommon.usf:

/** Cube map texture. */
TextureCube<float> ShadowDepthCubeTexture

Licensee also reported getting the crash because GBlackTextureCube was created with an incompatible format in regards to SampleCmpLevelZero. He had to replace GBlackTextureCube within FOnePassPointShadowProjectionShaderParameters (ShadowRendering.h) with a TextureCube of format PF_G16 (he just added another global TextureCube to the RenderUtils.h & .cpp)

Steps to Reproduce
  1. Open any project with d3ddebug enabled
  2. Load into a map (depending on the content you will get a crash see description for more details)

RESULT
Crash while attempting to load

EXPECTED
Map loads and the editor remains stable
