Hand/chest/head-classified cast and precast effects always attached to
the local player's character instance and bone-tracked it every frame,
so any nearby unit's cast kit appeared glued to the player. The spell
visual API now takes the caster's CharacterRenderer instance (resolved
guid -> instance via a new GameHandler resolver wired from
AnimationCallbackHandler); casters without a render instance get a
static effect at their world position, and impact kits remain
positional.
Add complete spell visual pipeline resolving the DBC chain
(Spell → SpellVisual → SpellVisualKit → SpellVisualEffectName → M2)
with precast/cast/impact phases, bone-attached positioning, and
automatic dual-hand mirroring.
Ribbon rendering fixes:
- Parse visibility track as uint8 (was read as float, suppressing
all ribbon edges due to ~1.4e-45 failing the >0.5 check)
- Filter garbage emitters with bone=UINT_MAX unconditionally
- Guard against NaN spine positions from corrupt bone data
- Resolve ribbon textures via direct index, not textureLookup table
- Fall back to bone 0 when ribbon bone index is out of range
Particle rendering fixes:
- Reduce spell particle scale from 5x to 1.5x (was oversized)
- Exempt spell effect instances from position-based deduplication
Spell handler integration:
- Trigger precast visuals on SMSG_SPELL_START with server castTimeMs
- Trigger cast/impact visuals on SMSG_SPELL_GO
- Cancel precast visuals on cast interrupt/failure/movement
M2 classifier expansion:
- Add AmbientEmitterType enum for sound system integration
- Add 20+ foliage tokens, 4 spell effect tokens, isSmallFoliage flag
- Add markModelAsSpellEffect() to override disableAnimation
DBC layouts:
- Add SpellVisualID field to Spell.dbc for all expansion configs
