Talk:Refract

Brushes

I'm pretty sure refraction on brushes wasn't possible in the original game. (It was a problem that was possible to fix as a modder; the render target wasn't being updated before the refracting brush models were rendered.) Perhaps they fixed it in the Orange Box version.

Refraction Map

Does the texture you use for refraction work in the same way as a normal map, where RGB equals XYZ?

And if so, what difference does the blue channel (Z axis) make?
