Multi Axis Rotation

Fixes purple/missing blocks from resource packs made for newer Minecraft versions

Modern Blockbench exports block & item models that rotate cube elements on any angle and multiple axes at the same time ("rotation": { "x": .., "y": .., "z": .. }). That feature was added in snapshot 25w46a (free single axis angles came in 1.21.6).

On 1.21.1 the model parser only accepts a single axis locked to -45 / -22.5 / 0 / 22.5 / 45. Any model using the newer rotation is rejected and renders as the missing texture block.

This client-side mod helps 1.21.1 to read those rotations.

What it fixes

• Detailed trapdoors, buttons, fence gates, signs, props, decorations that use free / 3 axis element rotation.
• Both block models and held/inventory item models.

Install

Client-side, Fabric.

1. Install Fabric API.
2. Put the jar in mods/.
3. Launch and enable your resource pack.

Compatibility

• Client only, not needed on servers.
• Renders through the vanilla bake step, so works with Sodium / Continuity / etc.

Known limitations

• UV lock on arbitrarily-rotated faces follows vanilla's axis-aligned logic; textures on freely-rotated faces may not lock perfectly.
• Rescale ("inflate to fill") is applied for legal single axis rotations only; multi-axis elements use their authored geometry without rescale.
• Built for 1.21.1. Other 1.21.x versions coming soon.
