Blender is an open-source 3D animation and modelling tool. It incorporates a full game engine, enabling you to create a 3D game inside the app. It has photo-realistic shading with support for Open Shading Language, and it provides shaders for glass and translucency. A comprehensive set of rigging tools makes posing characters easy, and a pose editor and sound synchronisation enable you to bring your characters to life.
