I’m pretty happy to here it will get better. I Currently have a bunch of models I’ve purchased online getting the error in unreal engine 4.5 “object has wrapping UVs”. They look great until I build the lighting. I even tried importing to 3DS Max, re-exporting as FBX 2013. Still that same message. They import fine into unity, no issues. Before (pre 4.5) I was able to generate unique UV’s to resolve the issue (As long as the model didnt’ have too many polys or else I got D3DXMesh Error) Just wanted to give you a heads up.
Also, really wishing this feature was added to make my life easier importing these models like it was in Unity Imgur: The magic of the Internet
