Yeah, I know what you mean, BB - on both counts. I'm a lot better versed in the busy with work arena than I am with shaders, believe me!

And on the other part, I can relate as well. I learn best by just getting in and screwing things up, then figuring out what the heck happened... Not really, but I've learned so much in the past year both by just messing with it, and with your help through tuts like this.

I'll have to look into that Matmatic thing. I've read about it in a couple of these forums.

Good luck on the work, and thanks for all the info!
