Just released SparkFXPreviewer v1.7.3 — a free Unreal Engine editor tool for real-time VFX preview and timing against animations.
Features include Niagara effects, sound cues, projectile motion (linear/arc/ballistic), and camera shakes — all without entering Play mode.
Built to speed up iteration for combat, abilities, and animation-driven workflows.
