Really Fast Paintings

Each converted painting is stored as one logical block entity, and the tiles a large painting covers become lightweight part blocks. Part blocks encode their offset and facing, so the anchor position can be reconstructed with plain arithmetic rather than lookup maps. Because converted paintings no longer act as ticking entities, the work of keeping them alive is removed, while large paintings still behave like normal wall decorations for placement, hanging support, collision and raycast interaction.

The mod uses a custom renderer that picks a level of detail from the projected on-screen size of each painting, with hysteresis so that paintings do not flicker between levels when the player moves toward or away from them. Painting dimensions and assets are resolved from the Registries.PAINTING_VARIANT registry, so variants added by datapacks work without hard-coded size tables. Distant Decorations is an optional integration and the mod runs normally without it.
