First time asking a question here ! woo. I've tried to look for an answer.. I must be missing something very basic. I started using Geometry nodes a few days ago (finally) I'm trying to scatters stuff on instances by vertex group located on those instances [![][1]][1] So we have those "building01" and "antenna01" objects I scattered building01 using a vertex group on the ground plan then random rotation, all good. Now, i want to scatter those antennas on the top of those building01 instances. On the building01 object i defined a vertex group called "roof" - First i tried to make it all with one geometry node but i cannot access the "roof" vertex group. -I tried to stack TWO geometry nodes modifiers (one for the first scatter of building01 and a second one for antenna01). But that just... don't work. -I tried to make a geometry node for the building01 object, i can scatter antenna01 but just like shown on my screen capture all the instances are identical. Which of course makes sense... - Realize instances doesn't help because i can't access the vertex group on building01 anyway :( That's it.. actually. This is a very simple example but then i could have complex buildings bases and scatter/display stuff on them using vertex groups. like antennas on roof , pipes on wall, etc. Thank you everyone [1]: https://i.sstatic.net/HUFIf.jpg Blend file : [<img src="https://blend-exchange.com/embedImage.png?bid=R2qMR72g" />](https://blend-exchange.com/b/R2qMR72g/)
