RIBMosaic is an IDE to connect Blender to Pixar Renderman®.
Pixie is a photorealistic Renderman renderer.
Ramen is a node compositor.
About Renderman:
Pixar’s RenderMan has been specifically engineered to meet the demanding challenges of rendering 3D animation and visual effects. This means RenderMan is fast, efficient, and able to handle an astonishing amount of geometric complexity along with offering cutting-edge effects.
Enjoy!! :RocknRoll:
