It shouldn't be necessary to make hundreds of trees, should it? My machine gets upset when I have 50 trees, and I have a 1.7 GHz with 256 MB of RAM. ;) Alley, I read that, and I have tried some variations on it in the past, but unfortunately it doesn't allow me to do the dappled lighting I want. Or, if it does, I am too stupid to know how to do it right.
