I'm trying to make underwater reeds for a scene in Blender cycles.
I have my reeds textured and ready, I'm using a particle system as a hair type and I've set it up so the "grass" covers my floor plane.
My problem is the grass is spread evenly across the plane. I want them to be in patches, clumped together and have the floor visible where they're absent.
A solution in my head would be for the particles to follow a noise node, tightened up using a colour ramp but I cant seem to figure this out, if it's at all possible?
Thanks for your help
