I realized that If I set CC4 to High Priority on Windows I get more "chances" to ORM Textures for Unreal Engine get exported correctly. But even with those "tweaks" sometimes it doesn't and it's very time consuming because I have to export 3/4 times to get the expected results.

Those issues started to happen since 4.4.0.

To reproduce the issue just export any Character from CC4 using 4096 Textures, Delete Hidden Meshes and Use Subdivide mesh.

What really happens with those ORM Textures is:

- They just don't get exported and other "random textures" are exported instead.
- It's really annoying because I have to do everything manually in Unreal Engine and sometimes I got even Hair or Clothes with wrong ORM not just skin,head,legs,arms.

PS: Since the ORM Textures are not in the files exported sometimes. It might be causing issues not only in unreal engine. But any similar software.

I was thinking this is a known bug and will get fixed, but the CC4 updated today with only Zbrush fixes so....
I'm sending you this ticket.

Thanks for the amazing software.
Hope it get fixed soon.
