Working in the TV/Film world, I'm having to constantly interchange 3d filetypes with other Set Designers, Art Directors, and VFX folks. .FBX has been the least headache of preserving scale and texture of models. A large share of Set Designers only use SketchUp for 3d, and draft 2d in AutoCAD, bringing their stuff into VW is ok with the SketchUp import, but sending VW models that have texture is damn near impossible reliably without .FBX.
I think VW is the ultimate tool for what I do, but a better seamless 3d exchange would make this an industry leader in my mind.
