I went to modify an existing multitexture terrain shader so that I could have dynamic lights affect the terrain, but I have no idea what I am doing. I have a lot of experience with programming, but I have never used shaders. I guess I just need to figure out where to start.

Currently I am using IceX2.0 to generate my terrain and I can't seem to figure out how to add the dynamic lighting to the shader.

In the end, I want to be able to create a HMP, have it textured, and have it be affected by dynamic lighting.

Any help would be appreciated, thanks a lot,
