Hello I can’t seem to get tessellation to work. I am running Unity in DirectX 11 mode and I am using the tessellation shader supplied with Unity. I’ve added a base and a normal map which have both worked fine. I’ve also added a height map by clicking “Alpha from Greyscale” however the edge length and height bars on the shader don’t seem to be doing anything. I’m guessing the problem might be because the plane I’m trying it out on has kept at the same number of vertices, I’m guessing more vertices are meant to be added? But really I don’t have much idea, it’s the first time I’ve tried this. Thanks in advance for any help. 
Have you tried it on a simple quad plane? That is the only way that I can get it to work for me.
