I thought Blender was the only free 3d modelling/animation software. There are more. From 1999 up to last month, I never tried typing in 'free' when searching for a 3d modelling software. I thought nobody would just give away their precious work away.
I downloaded and installed these two softwares, trueSpace http://www.caligari.com/ and Sketchup http://sketchup.google.com/ . How these two became free? Well, just google it!
