Can someone please point me in the direction of a good tutorial for doing trees in Bryce? I have looked at the one on Brycetech and it had some good pointers but I need something a little more detailed. I can make then but they just don't get me the realistic feel I am after...nor am I having much luck getting them the right shape. I just wind up going with what it gives me.
Additionally if anyone knows of any good, free, textures for trees around...I'd be much obliged.
