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

perf/fix: some little perf improvements and minimessage updates

fix: rewire Bundle-Everything, dead since the R4.0.6 updater rewrite

fix: NPE freezing models when a queued state is removed the same tick it's played (#352)

fix: allow dismounting models whose base mob has AI disabled (#347)

fix: clean up leftover data when a world unloads (#187)

Unloading a world used to leave a few things behind that slowly built up in memory and could eventually crash the server. This clears them out:

- Entity VFX now disappear (and follow their target) like they should, instead of lingering forever
- Invisible model bases no longer leave stray references behind
- Pivot/mount data is now released along with the model

ci: please ci i need this

ci: i hate ci/cd

fix: ci giving old jars

fix: state machine animation play/stop/query now take effect in the same tick (#221)

perf: cut per-bone-per-tick allocations in model tick and bunch of other fixes

fix: ModifyState now sets lerp duration, not the lerp progress accumulator (#348)

fix: gate player model resources behind Create-Shader (don't ship player_head.json when shaders are off)

fix: snapshot BoneItems read to fix "Item is null" race (#327)

actually log the model in `Unable to find model with ID`

fix: stop binding renderByDefault to blockbench eye-toggle (editor-hidden parts always hidden)

*my bad*

fix: use nanoTime for PseudoThread's tick guard so coarse clocks don't throttle the loop

fix: gotta make sure these are properly defined too (just in case)

fix: are we deadass (forgot to put "" for the viewrange mechanic)

fix: couple folia fixes

feat: mount support for non-Mob bases, p_N seat lookup, re-track health

Mount API improvements for driving custom mounts on non-Mob model bases (e.g. ItemDisplay vehicles). No default behaviour change.

- Custom MountControllers can now run on non-Mob bases. Override the new MountController#shouldEngineTickMovement() to return true and the engine will call updateDriverMovement/updatePassengerMovement every tick even when the model base is not a Mob. Defaults to false, so existing controllers are unaffected.

- MountManager#getSeat(String) now accepts the authored "p_N" seat name as well as the parsed "N", so you no longer need to strip the "p_" prefix before mounting.

- Mount health is now resent to players who re-enter tracking range, so they see the mount's current health instead of default full health.

Brightness mech now affect nametag bones

Initial 26.1 & 26.1.1 support

Known bugged feature:
- Core share player model works, but causes some items in inventory to not render. Mineskin player model still works though.
- If your model has elements that has out of bound UV (i.e. UV starts under 0 or ends above the texture size,) the model will render as error cube. Since it is a modeling error, a warning message would be implemented later

26.1+ requires Java 25. If there are any issues please tell Taiyou (cuz I will be gone for the week)

Fixed dummy sync location not syncing to body controller

clear force pair and hide api

Fixed ref animation not removable in state machines

Fixed projectile/aura taking priority over targeted entity when finding modeled entity

fix: read the bytes instead

perf: cache parsed bbmodels and improve I/O buffering

Cache BlockbenchModel between reloads using metadata+CRC32. Increase zip/read buffers from 1KB to 64KB. Import: 3.4s → 315ms, Zipping: 1.1s → 510ms.

perf: make pack generate faster

feat: meg client mod support

perf: reduce redundant metadata on spawn and cull transition

fix: guard interpolation delay with per-player snapshot check

Move snapshot computation before the interpolation delay condition so DISPLAY_INTERPOLATION_DELAY is only sent when the player actually has stale transform data. Previously, the delay was added based on the bone-level dirty flag alone, before the per-player snapshot was even computed. Also adds missing empty entity data guard to v1_20_R4.

fix: use UUID keys in SelectionManager to prevent watchdog hang

fix: reduce redundant metadata on cull transition

fix: Mount related desync issues

fix: OBB related issues

fix: re-do the folia bullshits

fix: Folia thread safety for mount system

fix: aura MEG attachment NPE - modeledEntity used before initialization

fix: forgot to commit these lol
