Somone can explain me how this node works and give some example?
It will read from the landscape, and sample the texture you tell it to in the details, and put grass when it sees that texture. Great 3m tuut here:
Basically, the Layer Sample node gives you a mask of the given layer. So, using that you can many things.
- You can send that mask to a grass node to add grass.
- You can use that inside a lerp node to blend some things etc.
