Is it possible to name a surface group on a mesh, for example 3 vertices that make up a face?
I want to be able to track the orientation of the normal for a face in order to decide if it’s facing the camera.
I am exporting from Swift3D.

Yes all geometric primitives have a name attribute that you can use for that. See <triangles>, <polylist>, etc…
