OK, I think I'm starting to get a handle on this Anything Grows stuff. I decided to back-up a bit, and just explore what the different controls do. I thought I'd share my approach with you, in hopes it might prove helpful.

Warning: These might be beyond basic for some folks, and even painfully obvious to others. However, sometimes I need information broken down into small, easily-digestible chunks.

Just in case some of you do too...

I started with a grid, and made a texture map divided into four colors: Black, White, Light Gray and Dark Gray. Of course, that was too boring so I mixed it with blue to make it more interesting.

I also made a solid White, a solid Black, and a solid 50% Gray texture.
