@TrickbagGames Hmm and UE to Rigify never gets deactivated some how? That is the only thing a can think of why bpy.ops.ue2rigify.remove_constraints() would not be found. Can you check?

[TrickbagGames]

I checked if UE to rigify was deactivated before and after the export and it was still activated.

@TrickbagGames I followed your steps and I can not reproduce this. Perhaps if your can get a blend that is consitently producing this output when the send to unreal operator is triggered, I can take a look and find the cause
