Create specific masks for Landscape Terrain

[davide445]

On this landscape albedo want to differentiate a mask where positioning the trees and one where there is only grass

Using a mask by color on the dark green still covers also the light green of the grass even with threshold 1

so that trees are placed also on the grass path.

Also trying to create a second mask based on the grass color nothing is selected.

Wrong approach and better work in Houdini where the data come from, or I'm missing some parameter that can improve the results.

Yeah, it's better to create the same mask in third party tool and reimport it so the terrain would know about a new mask.
