So I made a simple geometry node tree to create a tile with a hole. You can control the size of the hole (X and Y) from within modifier properties panel. Then I made a another geo tree that instances the collection of these tiles. Is there a way to use size of the hole (the X and Y values of the first Geo node tree) for example to instance cubes the exact size of the hole at the same spot of the other instances?
I have an update, if I use a REalize instances node, I get the two attributes visible in my spreadsheet but I have no idea how to use these values in my node editor. There is no Attribute node to just type "xx" or "yy" like we have a value node,a string node, or a material node. Solution for this one maybe?
