My existing build can be rebuilt with marble, but I would have to use the 2x1 blocks because I used 4x2x1 stone which means that my build with marble would cost me 4 times as many objects in my build which would technically reduce the performance of my base by 4x.

The engine has an object limit, and while it is pretty high, the engine also doesn't work well after 25% of the limit has been reached.

What I want is the Infested mine walls, they're like 8x8x1 marble, and all of the rest of the things in the game that are present but can't be built. I don't want to have to rely on mods to bring me things that are already in the game but I like to build in these types of games and it's tough to make a really nice build without all the parts. There's so many decorative pieces and I want them all! I like options.
