Your work is quite extensive and it creates a really good effect. I just use a dremel to quickly carve out cracks I have drawn by hand, and then a heat gun to make it more organic. I’ll have to try this though the effect is way cleaner.
Not bad for a scrap of foam I pulled out of the trash to do the demo on. lol I guess it will join the little patch of foam brick from the brick tutorial I have stuck to the back of my shop door.
I just stand them in a long row packed together as close as I can. The only issue I have is with ants wanting to make homes up in the inner support pipes.
