type 'chucknorris();' in console
That joke is old, it doesn't work
It doesn't really work. You can place bricks in blocked positions, and they will render, but collision will not work.
For particular building reasons, that wouldn't matter. Of course it would be a bad idea to have it in multiplayer-use. The best use for something like this would be overlapping vertical print bricks and maybe ramp bricks.
If you make your bricks work like waterbricks you can place any brick other than another water-type brick inside it.
it's glitchy as forget and you can't save the bricksmarble man released it iirc
