I am creating a dystopian city and I would like to create a series of irregularly shaped buildings from a displacement map of a wall I have downloaded. I have turned the displacement map into a series of individual cubes that I would then like to be able to arrange together to form a building. Here is an example of it in use as a flat surface (I have manually indented and extruded certain cubes to give the wall some dimension):
I originally tried using the geometry node and arranged the cubes around a shape that I modelled to replicate the building however I couldn't get it to work as all the faces intersected with each other, I couldn't get the faces to point the right way and I also couldn't get them to follow the shape of the building to look realistic.
I don't think the geometry node is what I need to get the building to work but I'm at a loss of how else to go about this other than manually arranging every cube individually. If anyone could give me some guidance that would be greatly appreciated :) If I have left any information out please let me know and I will add it
