Model Engine—Ultimate Entity Model Manager [1.19.4 - 1.21.11] R4.0.9

vroom vroom entity map lookup using primitive keys

Optimize ModeledEntity lookup by integer ID

Optimize TrackedEntityImpl via direct entity access

Optimize ModeledEntityImpl.getModels performance

- Cached internal `models` map to avoid `ImmutableMap.copyOf` overhead on every call.
- Invalidates cache on modification events.

Optimize BukkitEntityData location and boolean updates

- Deduplicate Location updates: Use a reusable Location object to query entity position. Only update the atomic storage if the location has actually changed, limiting allocations.
- Deduplicate Boolean updates: Check current value of isEntityValid and isDataValid before setting, reducing volatile write overhead when values remain unchanged.
- Benchmarks show ~26% improvement for location logic and ~86% for boolean logic in steady state.

Optimize BukkitEntityData syncUpdate tracking logic

- Lazily initialize tracking queues to reduce allocation pressure.
- Use incremental updates for syncTracking set to avoid unnecessary clearing and rehashing.
- Improves performance by ~19% in steady state benchmarks.

Avoid iteration overhead

Fixed segment disappears forever when scale = 0

Fixed player getting stuck when removing their last model in ModelMechanic

Added "track=false" parameter to Model Mechanic to disable displaying models to other players when disguised; Fixed `model{r=true}` on players

Add a `boneId` field and getter to the `DisplayBone` implementation so external plugins can reliably identify which bone they are interacting with via the API. This enables integrations (e.g., per-player glowing or bone-specific operations) without accessing internals

Fix Nametag's style not being marked clean. This slightly improves bandwidth usage (non-negligible)

Fixed model mechanic not working after logout on players when using pivot override

Fixed model viewself attribute not doing anything

Added `ch=true` as an alias for child in partvis

Most mechanics called inside of the `onStart` skill of a projectile or aura will now act on the bullet/attachment model instead of the caster

Added api for lod bullet stuff

Added api for setting projectile bullet and aura attachment brightness

Fixed animation timeline is imported even if empty

Fixed ModelPart randomly returning wrong location

Fixed animatemodel mech reapplying local transform

Bone local transform will no longer apply when copy=true since copy mode already has the local transform pre-applied

more moveTo overrides

Extend override move to config to all navs

refactor: compact import model logging & add setting to only print out for modedls with issues

Space to tabs

Optimization on model viewer tracking

aka Taiyou fixes my bad code :prayge:
