Things that would be nice to have:
1. A way to paint/color stone that isn't material replacement, like painting objects
2. Better, more precise stonecutting tools for fine scultping and design, such as creating detailed cutouts and sculptures
1. You mean to paint terrain? Yes, that would be great.
Though you can just craft a block with terrain texture and paint it
2. With the building system nothing is impossible. You can build statues with blocks and shapes. Along with free placement and rotation. But it's a challenge.
I'm not good at building such, i prefer houses castles And furniture.
however in order to really chisel or carve out details the size of each voxel would need to be much smaller. Resulting in impossible hardware requirements. Yet. Unfortunately
