Normals

[Jacky720]

Something is up with normals. They get loaded from KMS, they look fine in Blender, but then they get completely ruined on export. However, the exporter does seem to work (for cmdl at least, it's weird) because smooth normals created in Blender do work. So it's some kind of insidious import issue where the workaround is to throw out the normals and recalculate them (auto-smooth at 90 degrees seems to work well)...

Progress: It turns out Blender's vertex normals are actually assigned to loops, not vertices. The issue has been mitigated by using loop normals on export, but there are still minor differences that I assume are somehow the fault of Blender recalculating normals on application.
