Hi,
I have a simple question. What's the simplest way to scatter primitives of a mesh onto a surface? In the attached image, i have 6 primitives belonging to a single mesh which I want to randomly scatter them on a grid.
Thanks

“Simple” is super hard to define.
In the old world, where copy stamps would still be allowed, one could simply scatter points onto the grid (the same amount as primitives to be scattered), copy the geometry onto the points and then stamp the input to delete anything but the actual primitive and move it to the origin before the copy, so that every point would just have the respective primitive copied onto it.
Nowadays some places ban them, because stamps cannot be compiled and are thus slow, so you would need to do it differently.
Are they still allowed in your workflow?

Yeah I noticed copy stamps are not recommended, so I didn't pursue that route. Instead I saw this post [forums.odforce.net] which seems pretty intuitive. For now i'm manually connecting 6 groups (since i have 6 primitives in the example) to the switch node and it's working well, but I wonder how I can automate the random switching of primitives without having to plug them one by one to the switch node. Any thoughts?

Look into MOPs, they might have something that you can use to accomplish what you need:

PaQ WaKThis is pretty much what I was looking for. The expression on the blast node is doing the trick. Appreciated!
I would create an modulo ID based on the ptnum, and blast/copy the primitives on the points according to this @ID.
Not sure if it's the best approach, I'm already happy when things are working :O)
MidphaseThat looks interesting. I will check them out.
