Hi, 
I've been experimenting by importing CC3 characters into Unreal Engine 4.26.2 and I wanted to try out Path Tracing. But, when I turned that on, the character(s) from CC3 turn green! 
I don't know what is going on or what I am doing wrong. Does CC3 support Path Tracing for CC3 characters for Unreal? 
I've turned on Ray Tracing and it's on DirectX12.
