I made a procedural Overhead Sign Group Node. See .blend file below.

I have a collection of 5 blue panels which I distribute over the metal framework by creating a mesh line and points.

Now the order of the blue panels is the same for each individual framework. See images below.

How can I randomly distribute the blue panels on each framework in a different way?

I think this will answer your question so I'll just post it as an answer so I can post a picture.

This will give you a random number per index you can use to pick a sign. I'm pretty sure if the index is out of bounds (6) it will not instance on that point.

As you can see I have a bunch of joined individual geometries and it picks from those. enter image description here

  • $\begingroup$ Hi Haskell, Thanks for your answer! I tried your method in the blender file, but I'm not able to make it work. (on your screenshot some values are hidden behind a pop-up info). It doesn't seem to change the order of the panels. Probably I'm doing something wrong, but I'm not sure what. $\endgroup$ Commented Jan 25, 2023 at 15:07
  • $\begingroup$ Make sure pick instances is on. You can plug an integer in instead of index and change the values manually to see if it is making a selection. $\endgroup$ Commented Jan 25, 2023 at 15:15
  • $\begingroup$ I confirmed that it works. Modulo should plug into instance index not selection. $\endgroup$ Commented Jan 25, 2023 at 15:21
  • $\begingroup$ Thanks a lot Haskell, I managed to work out a solution that works using your technique: dropbox.com/s/wf5413qsszcfmv0/… I watched a video about the Modulo node, but I'm not quiet sure what it does here. Does the modulo node makes sure each of the 5 different panels is chosen in equal amounts? $\endgroup$ Commented Jan 25, 2023 at 19:13
