Pattern: EventTick → FInterpTo(Current=CurrentValue, Target=TargetValue, DeltaTime=DeltaSeconds, InterpSpeed=5.0) → SetVariable(CurrentValue=InterpResult) → [use CurrentValue for UI or material or rotation]. Key: FInterpTo inputs: 'Current' (current float), 'Target' (goal float), 'DeltaTime' (from Tick's 'DeltaSeconds' output), 'InterpSpeed' (how fast, try 3-10). The result approaches Target exponentially — it never exactly reaches Target (use Branch + Clamp if needed).
