Hi,

I'm looking for  proper fbx import settings in UE4. Binormals and tangents should be calculated in the pixelshader, not in the vertexshader.

So what does "Import Normals" in the fbx import dialog imply?
You import only the "Normals", means "smoothing groups" (hard/soft edges), or does it also mean to import "binormals and tangents" ?

Thx

    there is a setting to import tangents as well so I think you can guess one.

    But seriously... If you bake with Mikk Tspace, you only want to import normals. Non mikk tangent space baked meshes should be imported with normals and tangents imported.

    Yeb, I'm baking with Mikk Tspace.
    My (baking) FBX settings from max are: "smoothing groups" and "triangulate".
    So it seems "import normals" is only for the smoothing groups.

    Thx
