Salicin: Block Scale

A block that implements the IScalableBlock or IRotatableBlock interface receives scaled or rotated rendering and matching collision automatically, without per-block code. Block model rendering is transformed at bake time through a BakedModel proxy, and block entity renderers for chests, signs and similar blocks are moved together with their parent through a mixin into the block entity render dispatcher.

Collision handling covers scaling and translation: VoxelShapes are transformed to match the scaled model, and the translation keeps the rotated model centered. When a block implements both interfaces, rotation is applied first and scaling after it. Each block's pivot can be set so that scale and rotation happen around an anchor point inside the block. The library is configured through a mixin config JSON and works with rendering replacers such as Embeddium and Oculus.

The mod is a Forge 1.20.1 library with no configuration needed for basic use, and it is published as an alpha build for that single game version. It is client-side only, so servers do not need it, and it is released under the MIT License. It is not open source.
