With this Python script you can export data from Blender ( http://www.blender.nl ) to RenderMan RIB files. At the moment only polygons are supported (lights and camera as well). The polygons can have basic materials (color), vertex colors and st-coordinates (for textures). The script is running with Blender 2.10 and higher and needs a full Python installation (Python 2.0). The script will be updated frequently as soon as there are new features in the Python API of Blender.
