I am exporting a character to UE 5.3 and using Subivision Mesh.
If the subdivision Level is 1 or 2, then the character is successfully imported into the UE, but I see errors in the log, see file SUB12_Err.txt
If the subdivision level is 3, then the import into the UE ends with the crash of the engine.
For the log of this option, see file SUB3_Err.log
