One of the things you discover when you start doing 3D modeling for game development is that the tool sets of modelers vary widely - even more widely than programming paradigms between development environments (yes, arguable).
Last year, I introduced the developers of Shade to Unity. Now I have the opportunity to get a version of Shade 3D created specifically for Unity developers. What is it that you’d like to see in a 3D modeling/animation/etc environment to make it the very best for your development projects?
The first thing that comes to my mind is the ability to exchange files with the fewest possible steps, so its possible to see what your model will look like in the present project. What else?
