using a fractal texture or height map to control where V-Ray grass is on a mesh?:

[J450NP13]

I saw something like this but I cannot find it now. Is there a way to do this or did I see it for something else?

Could you tell us what tool are you using to generate your grass? If you are using VRayFur you could put Fractal texture in the "Density texture" slot. Note that you will need to enable "Alpha Is Luminance" option of the Fractal in order to work.

Thank you.
