Rendermans

Hey can anyone tell me how to use a renderman renderer with blender? Preferabley 3Delight, but it would also be useful to know Aquis and Pixie

The main integration of Renderman is going on here http://wiki.aqsis.org/doku.php?id=dev:blender_plugin

There are also other export scripts like BlenderMan and Blend2Pixie scattered around.

It all depends on your work flow. I personally use Pixie and wrote myself a very simple script that exports only meshes, since I do all the lighting and shading in renderman.
