I upgraded CC3 and subsequently started having problems with characters created under UE4 version 4.25.3.
The character is regularly exported to fbx and imported under UE4, when I try to do any operation with the characters exported after updating CC3 I get the following error in UE4 and UE4 resets: Assertion failed: AllocationId> = 0 && AllocationId <= 255 [File: D: / Build / ++ UE4 + Licensee / Sync / Engine / Source / Runtime / Engine / Private / Materials / MaterialInterface.cpp] [Line: 611].
All characters imported with the outdated version of CC3 work smoothly.
Unfortunately the imported characters after the update crash the UE4 program just by clicking on it.
As indicated by Miranda (RL), I attach link forum:
Before answering I wanted to carry out a series of tests. I created a new program with UE4 as recommended by you and I must say that the problem does not occur 8 out of 10. Unfortunately there are two out of 10 that made me think. Normally it becomes more evident when I start using the character by inserting him into a Blueprint Class, or I retarget an animation to him. To be careful, I reinstalled the CC2 version and created the exact same character with the same clothes and the same decals on the shirt. I can easily load this last character created with CC2 on my UE4 program and connect it within Blueprint Class and it absolutely does not create any problems. This confirms that the CC3 + version has problems, compared to the previous one which does not.
This is the error that UE4 presents:
Assertion failed: AllocationId >= 0 && AllocationId <= 255 [File:D:/Build/++UE4+Licensee/Sync/Engine/Source/Runtime/Engine/Private/Materials/MaterialInterface.cpp] [Line: 611]
I look forward to your reply.
Thanks for now.

I can import your fbx to Unreal successfully, please reference to attached image.
Could you recreate a Unreal Project and copy the Auto Setup into project folder, and try to import once again to see if the issue exist?
