Hi guys. Is it possible to shuffle picking up instances from collections so it can be randomized across different objects using same geometry nodes? I would like same mesh instance to appear only once when using instances on points but if I put random value in instance index it often spit out duplicate values.
Cheers!
It may be possible, but its not the type of thing I would want to attempt. 
A “shuffle” operation is very hard to do without using Python since GN doesn’t have List operations at the moment. The likely solution with current capabilities may be to run a Simulation Loop where instances get randomly swapped on each frame, and you run the simulation until there is sufficient variation.
Maybe someone else has a better plan on how to do this. 
Good luck.
You can kinda do this (on one object) by limiting your number of points to the number of collection instances:
It’s a decent start on an alphabet soup generator:
Hey guys. Thanks for your replays!
@SterlingRoth Thanks for solution. Will try it out later today!
