Michael,

>Additionally the .obj file format does not itself have any method of representing edge weighting so any transfer through .obj format will not preserve edge weighting anyway.

I thought the edge weighting could be something like Max's SubDiv Beta 9 script, where one uses a slider.
I'd rather see this for imported OBJ files, as opposed to relying on the ever changing proprietary FBX format.

Thanks for the consideration.
