There are A LOT of 'left in limbo' modeling apps out there on the net. LOL. So I guess it's just good sticking to the small utility side of things. XD

It appears mostly everyone is using Wings3D - I don't know how to work with it properly, to be honest.

It seems to work in the same way that Houdini does where everything is orchestrated by a bounding box.

Until I figure out how to get somewhere with it, it's been a great resource for converting Mod Tools and Lighwave (non-commercial versions) files into Wavefront OBJs so that I can play with them in Sculptris.

Filmbox to OBJ conversions do seem to degrade the geometry a bit though.
