This is the next tutorial in the terrain generation tutorial set.
This tutorial focuses on the shader code and gives some tips on how to create a shader to handle procedural terrains using vertex normals.
Also, it would be great if you guys could give me some tips on what else could be done to make the presentation of the tutorials better.
@Megalomaniak I will be going into the cave system generation in a couple of weeks since I have a few week's worth of tutorial content planned. But really appreciate the suggestion.
