How to Apply Tessellation to Terrain?

I have seen the pictures but there are no tutorials.
I REALLY Want to improve the quality of the terrain because it’s very spiky
Ha, I can’t even apply a shader to a terrain.
someone please tell me how? Both Things.

You have to first make a material and apply a terrain shader to that material. I believe the terrain shaders are under natural and terrain. You have bumped specular or diffuse. Go to the settings tab on the terrain. Put your terrain material in the material slot. There isn’t a tessellation shader for terrains yet. To make the terrain more smooth you can go to the terrain dropdown and go to resolution. In this menu you can change a few things. I believe that increasing height map resolution increases the quality of the terrain. Hope this helps.
