Hi guys, I'm trying to create a terrain with lighting and shadows, at the moment what I have is a flat terrain which uses a height map to change its y values and then tesselation which changes dependent on how close you are. This works all fine. However, now I want to add lighting and I'm super confused about it since all the things I see online use just a fragment and vertex shader, or those and a geometry shader. My current pipeline is vertex > tesselation control > tesselation evaluation > fragment. So when it comes to things like passing normals from vertex to fragment, I have no idea how to properly pass them through my tesselation shaders. Any advice would be greatly appreciated!
