Yes 3Delight is FAST, there is a drawback to everything I guess. Since BMRT became unavailable I feel this is the next best option in terms of affordabilty. It could even be the best option over BMRT due to the speed, but I dont have much experience with BMRT as most of my shaders dont work as I have the older version.
Blenderman is an amazing script, needs some tweaking if you know what to do, especially if you want to render DXF’s that have been loaded by using the “Open” file command. Each mesh’s name is prefixed with a “*” which causes hassles on Windows as this is not a valid character for a file name or folder. This can be fixed by fiddling with the code to strip this character and others out before creating the mesh files, but you have to be careful.
Also a point worth noting is that if you are using an image as a mapped texture, that image has to be in the /blenderman/default/textures/ folder, you cant just enter its path into the texture box, something that took me a while to figure out. By the looks of things it also has to be a .tif file also.
As far as help files are concerned, I dont know, haven’t seen any myself, best way is to view the generated RIB and read up on the Renderman spec and 3Delight.
If anyone knows where to get BMRT 2.6 for windows…
