In Unreal Engine 5.6, I created this explosion effect using Niagara FX, incorporating a SubUV Animation module with a 10x10 fire blast texture sheet. The explosion triggers when the third-person character enters a trigger box placed in the level. A blueprint setup handles the overlap event, spawning both the visual FX and synchronized explosion sound. The effect uses Spawn Burst Instantaneous to deliver a quick, dramatic burst. All particle behavior is finely tuned through Niagara’s Emitter and Particle Update stages.
