Understood. :-)
I usually hack the heck out of the resulting .pov file anyway.
Which reminds me, would it be possible to add an option to L3P so that it
produces just a basic model file, no camera or lights, to use as an include
file in a master file?
I do that a lot. Chop the camera and lights out, then cut & copy the final
Object line into my scene file.
