I'd like to have multiple layers of textures on my terrain. What would be the best way to do this? Is there any other way than blending?
And about blending: I render my first texture with depth testing enabled, and depth buffer writes enabled. For the second texture, I disable depth buffer writes, but what do I do with depth testing? If I enable it, wil the new texture be displayed nicely on top of the first, even if the depth coordinate is exactly the same as the first texture? Do I need some kind of offset ?
I'm not quite ready to learn GLSL, or something. I'll be very happy if I get this OpenGL 1.0 thing straight ...
