Blender For Windows v.2.60a

Blender, the open source software for 3D modeling, animation, rendering, post-production, interactive creation and playback.

Blender has proven to be an extremely fast and versatile design instrument. The software has a personal touch, offering a unique approach to the world of Three Dimensions. Use it to create TV commercials, to make technical visualizations, business graphics, to do some morphing, or design user interfaces. You can easy build and manage complex environments. The renderer is versatile and extremely fast. All basic animation principles (curves & keys) are well implemented.
In a few sentences, what is the GPL?You are free to use Blender, for any purpose
You are free to distribute Blender
You can study how Blender works and change it
You can distribute changed versions of Blender In the last case you have the obligation to also publish the changed source code as GPL.
Can I sell my Blender creations?
Anything you create with Blender – whether it’s graphics, movies, scripts, exported 3d files or the .blend files themselves – is your sole property, and can be licensed or sold under any conditions you prefer.
So I can make games without having to worry about the GPL, right?
Games created in Blender (.blend files) are program output and therefore not covered by the GPL. You can consider them your property, and license or sell them freely.
With stand-alone games however, any data that is included inside the actual stand-alone executable is covered by the GPL. If this is a problem then you should set up the stand-alone player so it reads from external .blend files. A common practice is to include a “please wait, loading…” scene in the standalone, and read level files externally.
The Blender standalone player or the game player can be sold commercially too, but you have to make it available under the GPL conditions.
So I own the copyright to all output?
In almost every circumstance for blender, only the code and other GPL’d files themselves are covered. Any output of such material is copyright the person who produced the output, in this case, the artist.
