Download Blender 2.57a

The Blender Foundation has released an update for version 2.57 of the open source and cross platform 3D program Blender, which was released a week and a half ago. The application is intended for 3d modeling, animation, rendering, post-production, interactive creation and playback. More information about the extensive possibilities of Blender can be found on this page are being found. This program includes the open source animation movies Elephant’s Dream, Big Buck Bunny and the end of September published cinder created. In version 2.57a a large number of bug fixes have been made.
