: tree woes

I had a serious render problem the last 2.5 days - work almost ground to a halt. Had issues with the paint fx trees - at one point it seemed like I had too many and the renderer kept crashing because it ran out of memory!

- finally fixed it but learned a few paint fx tips along the way:
1. to fix the warning about getUVfromPoly during render time - add source "getStrokes"; to the script preprocessing area in the common tab under render settings.
2. Increase light intensity > 1.0 to get certain paintfx to render visibly (when using illumination by real lights.)
3. render layers + paintfx: I had a situation in which the paint fx were not being properly assigned per render layer which resulted in each render layer calculating for each paintfx stroke even if it did not belong in that layer which resulted in maya needing much more memory than needed.
