Thank you guys very much. I like Stabby's solution to create only necessary faces, nice!

I tried to render it and here is the result (resized to 25%

Thanks for fast reply

I thought that cookie will have problem with overlapping geometry. But in my second attached example called “MengerSponge-Cookie.hip” I avoided them and it failes anyway.

Thx for example, I tried to extend it and it failed quite hard :-D I tried to subdivide the starting cube to “correct” number of divisions and it looked better. Than I added second cuts, everything was OK but with last cuts it was screwed (attachment).

I noticed that you use many “helper” nodes on the way which I don't know, I have to study more I guess.

Maybe, it would be better to create it from cubes but how to avoid lagging with many cubes on scene? Maybe edit with points?

Thanks

Hi, I've just started experimenting with Houdini and as the first experiment I wanted to create Menger Sponge. Combine it from small cubes is quite easy but after third iteration there are too many cubes that it is hard to even move with scene.

I realized that there is many useless faces so I wanted to create Menger Sponge using subtracting. Create cube and drill holes in using cookie node. First iteration is ok but second and third produces very crazy things.

I tried ti merge all holes and drill all at once which may not work properly so I used cookie node on every iteration. The model looks really weird, non-deterministic…

I also tried many primitive types. What I am doing wrong? Is this bug or feature? I am quite confused what is hapenning.

I am including some saves of my tries.

Thanks in advance
