There is Physical Shapes as a size constraint for large grids.

Vanilla armor blocks have the ability to combine simple shapes (such as plates and squares) that consist of nearly 50 blocks into a single physical shape. This contributes to the realization of large grids with simple shapes.

Blocks in this mod do not benefit from the functionality of this vanilla armor block. For simple shapes, the number of blocks can be reduced, but for Physical Shapes, the number will increase.
However, it makes a lot of sense to have shapes that cannot be simplified even with the functions of vanilla armor blocks, such as triangle corners and slopes, as a single block. Slopes made up of tons of blocks are one of the major contributors to Physical Shapes consumption. If you can make 5x5x5 sized armor corner blocks into 1 block, you save 45 Physical Shapes per block. This makes a lot of sense.

I have high hopes for this mod in dealing with Physical Shapes. Even if it's just a simple shape, I'd like you to add armor variations such as corners, triangular corners, and slopes. This can be a game changer.
