Has anyone created a conversion tool that works with other renderers/raytracers than POV-Ray? (Except Blender which I do not have time to learn.) Thanks.
You can export to pretty much any renderer using blender as a convertion tool. There is also a 3ds max exporter in Ldview.
But if you don't want to learn tools like Blender, I would say PovRay would be the best choice.
