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/ Source / Runtime / Engine / Private / Materials / MaterialInterface.cpp] [Line: 611].All characters imported with the outdated version of CC3 work smoothly.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.
