Ok, so you must obviously be on one of the experimental branches (like the spikeyxxx I know and love) because Simon T. approved the use of the replace/create just recently and I don’t see it on the official release in 2.92 and was trying to place but I only end up with 1 instanced object.
Did you instance that whole board array there with that new Replace/Create functionality? I don’t see an array modifier on that object, only the Geo-nodes.
Okay and on to my next question: let’s say we modeled in some cuts and damage instead of texturing everything (just trying to wrap my head around this new work flow). For example there are 3 boards with enough variation that you get a total of 6 sides to use and rotate for tons of variation: I’m thinking about random-run instancing between the three objects in a collection and letting the instancer geometry nodes handle all of that and throw in a random value. It could pick one of the three boards and rotate about the local x axis 180 OR NOT and rotate around the Z 180 OR NOT and Possibly the Y 180 OR NOT and you would have all kinds of combinations of instances from geo-nodes, correct?
Something similar to this posting only using Geo-Nodes:

You would get some increasingly complex floor board or tile or shingle structures that way in my mind.
