The other solution would be to fully model a leave, which would lead to a very high polygon count tree.Mirrornoreply@blogger.comtag:blogger.com,1999:blog-7277449027963623452.post-51931365025386439592012-06-20T01:03:46.747-07:002012-06-20T01:03:46.747-07:00@mirror, sometimes you want a part of an object to...@mirror, sometimes you want a part of an object to be transparent, or some gradient.

I'd definately be able to make something more if you can get it working with the 64-bit or just want a different style.
