Stone

Stone is one of three basic materials in Smash Hit, as well as being a structure. Stone is used for (but not limited to) the room, floor, ceiling, walls, stands, and decorative stone (on tiles).

Crashing
It is possible to crash into stone in the Random Rooms Mod, when walls seperating Local Multiplayer rooms become directly in the center view, and therefore block the player. There is nothing the player can do about hitting stone.

Crystals
The stone sometimes glues the Pyramidal Crystals to their base, but if they are not glued (i.e. can be knocked, especially on metal Moving Columns, which do not stick, or the blue lines in Checkpoint 2 stage 2), then in rotating rooms that do not usually rotate, (again from the Random Rooms Mod), the pyramids will fall off.

Texture
The texture of the stone is considered its tile.
