Note that composite rotations are not allowed, only X, Y and Z axis rotations. Such a group can be treated as one rotating object, and used if bigger doors or rotating objects are needed. The way a block or group rotates depends on the hinges used. If the rotating block is not connected to a hinge, it will act as a normal, 0.125 units wide building block. Summary Houses or any kinds of structures can be built from building blocks.
Blueprints allows players to easily design houses and help to automate the building process.
Building blocks are typically tile sized. Materials are Atlas objects that specify textures to be used for different sides of the shape and other properties. Building blocks are rendered by the clients. 2D clients keep a cache of rendered blocks, or render them directly using 3D techniques. Building blocks can be placed freely, but snapping to grid edges is recomended.
