Blender embeds Python 3, which can be used to write add-ons, tools, extend the interface, rig characters and automate tasks.

Blender runs the Cycles path tracing engine under the hood. Cycles is a very powerful rendering engine capable of full path tracing (light fall off, caustics, volumetrics). It is mostly compatible with OpenCL and CUDA rendering, and is implementing mycropolygon displacement features. The upcoming release has a viewport engine called EEVEE whereby you can see and interact with your work in render mode in real time!

Blender is licensed under the GPL.

The trick with Blender is to get used to its usage philosophy, as it keeps consistent through all the application. Once you get it, every feature or addition is learnt naturally, almost effortlessly.

Support lots of modern 3D formats including DAE and FBX - ideal for game developers.

Blender provides a full rigging system, and automates animation by interpolating between keyframe positions.
