tutorial, we can do some cool shader, because the second part we'll start using the cool technology of multiple textures, normals, and so on. In the second part, we create a shader that implements the snow effect, modifying the model to show different effects depending on the extent of the snow. In the third part we improved our shader to mix the snow at the edge of the rock. In the fourth part, we use black edges and gradient textures to create a shader with a cartoon effect.
