Proton scatter on Terrain3d

Godot Version

Question

Anyone familiar with Proton scatter? I know how it works for simple things but now I want to place trees in a range of 500 and there is water and land. Is there some way to only place on the land? So water is automatically not seen as a place for trees?

Adjust the proton scatter shape so that it doesn’t get into the water. As an example: Use square shape and keep square shape above water level. Another solution is to use the negative proton scatter shape.
