My buddy is needing me to put together a small farm of rendering boxes but I haven't worked with these types of apps before.  I have read a ton about the RenderMan format and RIB files.  He is needing sections of about 6 minutes rendered.  Would that be one RIB file?  Or does a RIB file just describe 1 frame?

Also, he is making his movie in 3D Studio Max.  What is the suggested work flow for getting it rendered?  Would you simply convert the file to RIB and then render with Pixie?

Thanks a ton for any advice you can give!
