I'ts not too difficult to incorporate LGEO and L3P in the same POV
file. I've done it once to get a high level of details in a wallpaper

(I was surprised that noone mentioned this.)
What you basically need to do to cram LGEO parts into L3P is to scale
them up by a factor 25 and mirror and rotate them to fit. (Yes, they
actually need to be mirrored too.) No offset should be necessary.
Incorporating LGEO parts steeply increases the quality of the image,
IMO.

Good idea, I have thought of it myself too :-) But I have postponed the implementation because I was hoping for an integration of LGEO and L3P: the effort writing POV replacements for LDraw parts naturally belongs in (...)
