1) I've noted that if You've a texture image invoked in more places
inside PovRay scene
it'll be loaded more times wasting machine memory.
I've implemented an image caching system that will load images ( all
kinds ) only once.

2) Polygon decals are not handled by Povray. There are cases where
You've multiple
overlapping polygons that must decal in a given order. I've introduced
an optional "seqnr"
attribute to polygons that will be checked during intersection test
compares ( when Z
intersection equals ) to choose the correct polygon.

If You're interested I can post You the code.

Of course we're interested. If you post the code, please post a few
example pov files that take advantage of these features, along with
any instructions you might want write for us.

Thanks,

Yes, I've noticed this, too, when I coded a szene with a few hundred
blob people :-(.

I think this would be a valuable addition.
