Blender custom normals & Smoothing groups
I'm slightly confused. I've read a couple topics from some years ago stating that hard edge importing would be easier to do when Blender gets custom normal support (which makes complete sense).
I looked up "blender custom normals", but I'm not getting many concrete answers on whether Blender has support for them or not. There is a normals tab under the "Object data" category on the right hand side, and there is a "Data transfer" modifier which lets you create face-weighted normals, but I'm not sure if this is what Artfunkel was talking about.
Is there enough custom normal support in Blender to be able to import smoothing groups?

Blender fully supports custom normals, as seen when importing DMX files or importing SMD files with "preserve normals" or whatever it's labelled as checked.
However, due to the nature of Blender not liking to merge vertices with custom normals, and SMDs consisting entirely of separate triangles (unlike DMX), you can't both have custom normals on imported SMDs and have the vertices of SMDs welded together, with the default being to weld the vertices.

Ah. I hadn't updated my Blender in a while, and didn't see that feature.
I did some looking, and couldn't find any way to select duplicate vertices- if you were able to do that, you could mark them as sharp then hit "remove doubles". That would be a quick fix to this issue.

Yeah... of course, except if it was to be done for all vertices of a >10000-triangle mesh (thus with >30000 vertices) upon an import.

Fortunately hats are 1400 at most, not sure about weapons. I found a couple scripts that didn't spit out errors that did warn about high-detail meshes, but none seemed to work.
