thanks too! Definitively those functions go to my shader function library

The blue channel of a normalmap can be easily computed based in the relation between sine and cosine or Pythagorean trigonometric identity:




Of course, it will be always positive.

I didn't actually do too much in that thread, just took advice from others and tested stuff out. From now on I will post about my tree work here exclusively, and if I do come up with some good stuff, I'll share it with the community. But understand, it may take me a while because I'm just doing it for fun.

I like the tree, looks nice. I doubt it will look better with normal mapping.

Thanks!

We'll see. I'm going to finish up the tree. I still am not happy with it, and then start applying shaders. (The tree already is looking quite a bit better)

What I'd like to get out of normal bump with specular:

1. Bark always looks good with normal mapping.
2. I'd like to get a "wet look" with the specular applied to the leaves.

First I'm going to finish the tree and all the maps, so I can test the finished product.
