I have three basic geometries that are copy stamped along the points of a grid.
What I need is for them to alternate randomly.

So far I have the three, for clarity's sake lets say a pyramid cube and sphere, plugged in to a switch. I can manually alternate between them using value
0=pyramid
1=cube
2=sphere

When I copy stamp, only pyramids, cubes, OR spheres show up. How can I make all three show up simultaneously?

Thanks!

Sorry, I misread your question in the first attempt to respond. You'll have to use copy/stamping technique. This video here shows exactly how to do it:

If you still have questions afterwards either ask here or search the forum as it's a popular theme.
Cheers

You can stamp this expression into a switch.

int(rand($PT) * 10) <<< in this case 10 is the number of differing inputs

The video is a good begining video clear and to the point.

Since I was trying to switch between 3 specific geometries in a switch “int(rand($PT) * 10) ” within the copystamp function worked.

Thanks sl0throp and rafaels!
