If I have a node tree for scattering for example a grass clump object onto a plane using instances, and then want to add another copy of that modifier but with a different type of object, for example rocks, the second modifier uses the result of the previous modifier and scatters tiny rocks on the grass clump instances as well as the plane. (there’s no make instances real node, if that makes any difference).
I can circumvent this by using a vertex group, and limit the scattering to that, but I feel I’m misunderstanding how something like this is supposed to work in general.
In short, if I want something like multiple particle systems but in geometry nodes, am I supposed to have multiple modifiers somehow (and if so how?), or one single huge modifier with everything in it as node groups, but that couldn’t be reused as easily?
