I've spent four days trying to import a character correctly, which isn't possible in Unreal Engine 5.6. The plugin isn't working. Furthermore, converting a rig to Unreal Engine isn't possible. The body is a sponge. I've tried in UE 5.5, 5.5, and 5.6. In other words, I can't get it to work in Unreal Engine. I'd like a refund.
