Really big? It does not seem so big to me, one of my first models
yeeeeeeeears ago (a c64, done on a p90, 8mb of ram with lightwave 4)
was only 50% of that size... Btw it's still something to test...

Well, as U say in your faq (i believe it's yours, am I right), it is
possible using a trick... As U surely know many things are possible in
this world... For example, I could do oop with plain C, but I don't
say that C is an OOP language or that is supports OOP...

I'll try to convert that and I'll tell you the resoult ok?? Or mabye
I'll do something else and send the scene to you, mabye with form
(that has a support for povray output too) as I'm experimenting with
it lately (but I've only used vivid3 to raytrace form scenes)
