Description

-When a clothing asset is applied to the mesh, the vertex color(s) change to solid black
-Can be removed by right click Remove Clothing Data
-Crashes in Main-4.20
-Can't be tested in 4.17.2 due to this feature (for clothing assets) was not implemented at this time
-attached FBX file was exported out of UE4
-Project file is cleaned up version(original version is available on Answerhub)

Steps to Reproduce
  1. Download attached project
  2. Open Material(See the Vertex Color node)
  3. Go back to editor and turn on Show < Vertex Colors(See vertex colors)
  4. Open Mesh
  5. Section Selection
  6. Select mesh < right click < Apply Clothing Data
  7. Select SK_CH_Gang_AA_AA_Clothing_0_LOD0
  8. See mesh turn completely black
