I know, but I was talking about the three libraries in the statement
above, not L3P.

True.

Exactly.

This is exactly the reason for joining efforts: to handle all parts, yet
use the best quality parts where possible. For example, an LGEO plate
has the little holes on the bottom under the studs, making it much more
realistic than an L3P'd plate with no little holes.

L3P already uses primitive substitution, so it would probably be easier
to add a call to LGEO from L3P. While I appreciate your efforts in your
coverter, I believe your true forte is your realistic parts library. L3P
is easier to use than L2P: the camera and lights are easier to place and
there is a quality switch to make processing faster. I think time would
be better spent trying to combine efforts rather than trying to duplicate
all the pros of L3P.
Combined effort could lead to one amazing program instead of having
many competing slightly lesser programs. L3P, which I'm pretty sure is
the most commonly used, can use some improvements, such as the use of
.inc files for primitives and parts, more realistic finishes, and maybe,
more realistic lighting.

To be frank, I haven't used L2P very much, because there are always a
couple parts missing. For the landscape, though, L2P, being simpler than
L3P, didn't run out of memory, so it was my only choice.
I hope I haven't offended Lutz or Lars, I just tried to share my view on
the issue.
