Texture tiling?

I don’t know exactly if it is the right term… I have a complex terrain and I’d like to put texture onto it to simulate grass, rocks and snow and whatever else. The question is: how can I achieve the effect of a continuos blend between the different textures? If you can get what I mean then you’re super smart and I thank you in advance. :slight_smile:

But tex env combine si really outdated by GLSL, so do not copy the code, only if you target GF3-4 video cards :slight_smile:
For GLSL, the OpenGL Shading Language (Orange Book) is great, with ideas on terrain mapping.
