Summary

• Render Bedrock custom entity geometry in the client using ViaBedrock's parsed resource packs and evaluated render controller state.
• Cache resolved geometry and texture combinations so render-state extraction does not repeat that work every frame. Invalidate the cache when resource pack storage changes.
• Convert Bedrock's absolute bone and cube pivots to parent-relative ModelPart transforms so nested rotations use their Bedrock pivots.
• Apply Bedrock player skins, capes, and custom player geometry through the addon's existing skin provider.
• Keep ordinary interaction entities invisible, publish entity render state safely across threads, and clear published actor state and player skin textures on disconnect.

This stays in viafabricplus-bedrock. It does not require ViaBedrock changes or the separate ViaBedrockUtility mod.

Validation

• ./gradlew build passed.
• ./gradlew runClient reached resource loading and a local world without a mixin or render startup error. The development client was stopped after 75 seconds.
• The development client uses an unauthenticated player, so Galaxite and Hive gameplay remains unverified.

In-game testing requested

• On Galaxite and Hive, check custom entity shape, nested bone and cube rotations, per-face UVs, textures, distance culling, and render controller changes.
• Check classic and custom geometry player skins, slim and wide arms, capes, and skin updates while connected.
• Disconnect, reconnect, and reload packs to check texture and model cleanup.

Scope of this draft

This ports the utility's custom entity rendering and player appearance features. Persona skins remain unsupported, as in the utility. Bedrock animation controllers, animation trigger packets, and material variants are separate work and need in-game examples before this is ready to merge.
