Blender3D and Instintive Blender
Blender 3D is an outstanding free modelling software. This addition by instintive mediaworks makes it better.
You may be familiar with Blender 3D, the open source modeling, animation, rendering, and post-production package from the Blender Foundation. If you have used Blender for longer than a few weeks and miss some aspects of the old pre-2.3 user interface, or if you are looking for some interesting features to improve your 3D experience, you should get to know instinctive-blender, a fork created by the small German company instinctive mediaworks.
