Open Simple Frames

The mod follows the idea behind Carpenter's Blocks: a framed block keeps its own shape but shows a texture borrowed from a different block. Instead of storing a full model or texture in a block entity, each frame stores a single number, a texture id, as an extra block property. A player uses an item in hand to assign the id, and every frame that shares that id then renders the same texture.

The framed blocks cover up to three sides of a block and include ramps, corner ramps that act like stairs, partitions that behave like walls, fences, doors, and giant blocks placed in 2x2 or 4x4 arrangements. Some blocks render taller than a single block, one up and one down. Most are crafted with sticks. Open Simple Frames runs on client and server, so the server and every player need it.
