Rukhanka swing animation: PlayerRigTools builds a procedural Root-bone PlayerMeleeSwing.anim and adds an IsAttacking param + MeleeSwing state to AC_PlayerTopDown (mirroring the enemy attack recipe -- no authored Synty Generic melee clip exists). PlayerAnimationDriveSystem pulses IsAttacking from the replicated MeleeCombo swing window (local + remote, NetworkTick wrap-safe, re-triggers per chained hit). CombatFeedbackSystem flashes a procedural cone slash-arc mesh matching the LIVE cleave range + half-angle on each swing (finisher wider/warmer) -- the arc IS the range telegraph. Addresses 'range isn't clear + no animation'. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
