I have a vertex group made using the Weight Paint and I am using a Geometry Node to distribute an object across the plane. How do I make the Geometry Node use the vertex group to distribute the objects?

The idea is that there will be fewer objects on the lighter parts and more on the red areas so I how would I connect them?

you can do it like this:

enter image description here

Important is the input value of the group input as float value, put/choose the name of your vertex group in the modifier. Plug your input value in the density (you often need a multiply because vertex just has value from 0 to 1)

  • $\begingroup$ Hi Chris I can't get it to work snipboard.io/Ng4WSi.jpg What did I do wrong? It's still showing in the blue area with same density as the red area. $\endgroup$ Jan 3, 2023 at 12:27

    $\begingroup$ Thanks, @Harry McKenzie works if put Named Attribute Node for input of multiply and select vertex group $\endgroup$
