this the first time I write on this forum.
When I try to import my fbx model in UE, I get these two error messages:
Wall has degenerate tangent bases which will result in incorrect shading. MikkTSpace relies on tangent bases and may result in mesh corruption, consider disabling this option
Wall has some nearly zero bi-normals which can create some issues. (Tolerance of E-4)
I use Unreal Engine 4.18, the latest version.
Also, I created my model in 3ds Max, I’ve assigned l’Unwrap modifier and exported in fbx.
Where these problems come from?
