TIGs OBJ exporter works perfectly, checked and re checked.
I can export complicated scenes into blender/cycles for rendering.
Blender now supports collada (the new fixed version I mean). So, I can import export in SU without issues.
3ds importer is also workable though the limitations (64k faces for single mesh, 8digit names for textures)
This last is broken on all OSX free SU 8, works well in SU7 free.
But, as long SU keeps exporting ridiculous geometry, giving no control to the user on this matter, who really cares?
I started using blender as an assist app to SU. UV editor, organic modeling.
Then, after cycles render engine implementation and the new blender UI, I started using SU as an assist to blender, importing there.
Meanwhile, I learned blender, new great tools similar to SU and much more advanced came. So, you see my point π
