in order to have a single list rather than few threads, here is our list of different 3D modeling packages. We try to update the list whenever new stuff appears, so every user can share new links and impressions, and we will add them to the list.
We focus more on indy style development which usually requires a package to be free or rather cheap in compare with high packages. Also mention any student or indy licenses
