Hi there

I am new with TG, I am using TG 2 Deep, I try to put a population of tree in a mountain from a ski resort, but I cant apply a mask over the project. and all the mountain is covered with trees, even when i use a map shader based on Bigben file

You'd have to place the loaded image map shader (with the right size) at the right coordinates, then blend the population by this mask. If this is what you mean? You could also use a painted shader.

To test the image map shader plug into an extra (and last in line before planet) surface shader color input.
