[Papervision3D] Performance Issue with flip down tiles

I think I've just about sorted this now, it was a combination of things
really (like you said).
First thing was to stop using MovieMaterial and to use BitmapMaterial with
bitmaps created from the tile movieclip.
Then it clicked that I could use just one MovieClip per row to create the
bitmaps, reducing the number of MovieClips from 100+ to just 6. The bitmap
stuff hogged a bit of memory, but according to DeMonsterDebugger I've got
the fps averaging at 28 now (which is much better).
you can see a preview on http://office.coolpink.net/ian/innovator10 (the
site is in the middle of chop at the moment so a lot of it isn't
I'm pretty chuffed with how this has turned out, though it's one of those
projects that doesn't inspire awe in the viewer because it seems so simple!
Needless to say it's been a bit of a learning curve for me with < 6 months
Cheers for the help!
