How do i make a clearing in a forest.
I tried using the simple shape shader that makes a flat spot in the Terrain and got nothing.


The Density input expects greyscale (though it will interpret colour as greyscale) scalar data to determine masking. 0 (Black) is no population instance, and 1 (white) is probability of population instance (depending on object spacing, seed, etc).

You'll want to take that simple shape shader you're using for the terrain, and also apply it to the density input of the populations. But you'll also want to invert the density, as the simple shape you want as a clearing is defining with 1 (white), so it'll want to constrict the populations to the simple shape itself, instead of the other way around.

Have a look at the following articles on the wiki:


Here's a quick example of how I usually do this.
