When to Load

Load when implementing character animation, particle or beam effects, tweens, camera feedback, or visual cleanup.

Load tracks through an Animator on a Humanoid or AnimationController; set AnimationTrack.Priority deliberately.
Use GetMarkerReachedSignal() for named gameplay or presentation cues, then disconnect or replace the listener when the track ends.
A burst ParticleEmitter usually has Rate = 0 and uses :Emit(count) with a bounded lifetime; use pooling for frequent effects.
Beams and trails need two attachments with a stable world-space relationship and a cleanup owner.
Tween a bounded set of properties with TweenService:Create; cancel or destroy temporary effects when their owner ends, and use Debris:AddItem for simple lifetimes.
In Server Authority projects, keep synchronized animation logic in RunService:BindToSimulation() (requires Workspace.UseFixedSimulation enabled in Studio), query current tracks instead of caching handles across rollback, and make predicted effects reversible.
Profile particle counts, lights, post-processing, and per-frame camera work on the target device class.
