Thank {you} if you implement it ;-) - I'd hate to do all that work over again.
BTW if you're able to incorporate that function, it would be nice if you can
merge individual submodels since more than 90% of mine are usually just angled
sections that is completely locked in place (and some functions may not be
relevant for the animation task at hand - like the opening of landing gear and
cockpit in a dogfight animation)

I guess that sorta answered my question, you lost me completely in the rest of
the paragraph ;-)

I've been working with simple rotating POV-animations earlier, and one of the
most annoying things about L3P is that you can't edit the output format - and
having to manually change the ambience and radiosity-settings (and possibley
flawed colour definitions of new colours) for 60 individual POV-files each time
was one of the main reasons that I gave up.
So any new adjustment possibilities you can add to the output file will be
appreciated.
It would also be nice to be able to set the quality-level for the individual
actors, so you set the quality of ultra near mocs to 3 (studlogo), near mocs to
2 (studs) and everything else to 1 (no studs) - you can't even see the studs on
stuff 1-2000 ldu's away, so there's really no reason to waste CPU on them.
