I have a simple node setup where I place some objects (grass collection) on a mesh if the z normal value is above 0.9. I would like this to follow a noise pattern (like the voronoi) such that it clusters together in some parts and to be completely absent in others.
I've tried using the Poisson disk option and control the density frac with the output of the noise node. This doesn't work and I don't understand why. The output from the noise is between 0 and 1 and the input to density is between 0 and 1. Is it taking the average instead of calculating it per point?
What are the alternatives for having multiple conditions for selecting points?
Thank you Chris for providing the exact setup I was looking for. I didn't think about using the color ramp.
Also, Gorgious pointed out a very good problem! I was indeed only using a plane mesh and forgot about adding subdivisions.
Thank you very much for your help!
