When I import my skeletal mesh into unreal there is a weird lighting effect that happens to the mesh. In blender I have it set to flat (no smoothing) and just in case I also have all of the tris edges set to sharp. When exporting I am using the Better FBX exporter add-on as I have consistent issues with blenders normal fbx exporter when exporting skeletons and skeletal meshes. Below I’ll share the images in this order. Blender view, blender edit view, blender Better FBX exporter settings, unreal engine blueprint view, and finally unreal engine viewport view (in game)

As you can see the butt on my character has really weird lighting and no matter what I do to the normals this problem persists. Lumen and nanite are disabled. I have recalculate normals and tangents disabled when importing into unreal. I simply cannot find why I have such weird lighting on the character. I have even tried completely rebuilding the characters normals and tangents within the skeletal mesh editor in unreal and nothing seems to work.
