just experimented with particle placement textures for a gradient hair grooming. Painted the eyes white to see if the hairs change accordingly. Nothing happened.
Here are my preferences in particles and textures (the mesh is UV unwrapped of course):
What is the wrong prefernece? I already fiddled around but none of them does remove hairs only in the black or the white area.
Big thx to anyone which has an idea how to get this right.
PS: Doing anything to the values of Density/Length has an effect, but it is NOT recognizing my texture.
