[Addon:] Send to Unreal Steps to Reproduce the Problem: In Blender, add a Mesh of Suzanne, then Push Assets to Unreal https://github.com/EpicGames/BlenderTools/assets/27040/5d080c78-f6d4-45bf-834c-caab6f128ece

The problem is immediately apparent with flat shaded objects that have curves. But I've also encountered shading issues when using smooth shading.

Here: blender_p85p5Qwbj2 I have a mesh that looks fine for the most part in smooth shading, but some rounded corners have shading issues.

Here's the blend file for the mesh above: RigMan.zip

Error Log: no errors

OS: Windows 11 Addon Version: 2.4.3 with a patch by JoshQuake to get exporting working in Blender 4 Blender Version: 4.1 Alpha (built from source) Unreal Version: 5.3.1

This isn't a bug. The character needs to be unwrapped. Here's a quick test. After making seams and unwrapping, the shading is fixed.
