How can I instance object on points of another geometry, but limit number of points used? Here is my current node set up:
I want to use the Selection socket on Instance on Points node, but I have no idea how to use it. I tried Noise Textures, Random Values and can't figure out how to randomly limit number of points used?
Is there a way to get ID / Index of each point and then randomly select 40% of them for the Selection, to Instance Cubes on the base Mesh?
just plug this into your selection of your point instance node:
This won't give the "exact" amount, but a good approximation.
Chris answer is simple and efficient way to "cut" through number of instances on points randomly.
There is a different way, if you want to have some pattern / texture, when instancing on your base mesh. Somehow, when I first tried doing this with Noise textures, I did not try it with Noise + Color Ramp nodes and it did not work.
Here how it looks now:
Noise Texture with Color Ramp:
Musgrave Texture with Color Ramp and so on:
