PyMOL can save both VRML2 (.wrl) and native PovRay versions of the current scene via the save command. Limited support for Maya .OBJ is present now as well (export bug fixed in current open-source code). VRML: save scene.wrl POVRAY: save scene.pov MAYA (triangles only, w/o coor) save scene.obj However, for some scenes (on modern multi-core hardware), it can take more time to write out & read these rather verbose text files than it does for PyMOL to simply render the scene using its own built-in raytracer...

With regards to Povray, I had mentioned that program as I had hoped that you could use a povray file generated in ccp4mg/povray/etc and then somehow read that into blender for futher editing (and make my life much easier - editing povray files to alter figures is a real pain). Blender can render figures using its own machine, with YafRay, or export it to povray format. >From what I've read, VRML format is not a good one, as for some reason blender runs really slow after reading these files in.
