I don't know which section of the forum this is supposed to go in, but since it's an FBX from iClone 7.21 to Unity 3D 2018.1, I am thinking here in Technical Issues.

Okay - the problem is that when I export an avatar to Unity 3D, from iClone FBX, the materials brought into Unity are all grey/white. 
If I export FBX, from iClone to 3DS Max or Unreal Engine, the imported figure comes in with materials.
One question -
How to get materials embedded 'in' character over to Unity 3D?

Thx!
