I have a fairly simple geometry nodes setup that instances tiles on a grid, allowing for random rotation (constrained to 90 angles) and tile ID (there are 12 designs of tile).
I want to create a number of these tile panels (all different) so that I can instance them along a line. I saw in this thread there is a possible way using repeats to generate the tiles.
But I’m not quite sure how this works - where do I put this in my node tree? What goes in the repeat zone? Can I still keep my input group controls?
So you want to generate the panels procedurally too? I don’t know what version you are on, but there was a “for each element loop” node added recently you might want to have a look at.
Simon Thommes explains it pretty well in this video:
I put the initial wall panel setup in a group for clarity, and then the only slightly tricky thing was figuring out how to get access to the random seed to be able to change the generation of panels from the modifier stack. To do this I just had to take the index of the “for each element” node and plug this into the seed of the random number for the rotation and panel ID nodes, inside the group:
