What problem does it solve? Configuring the Decentraland SDK7 ParticleSystem component involves dozens of interdependent fields, non-obvious rules (Transform.scale does not affect particle size, prewarm requires loop, faceTravelDirection overrides billboard), and engine limits like the ~1000 particle cap. This Skill provides the complete field reference, emitter shape helpers, burst configuration, and 17 tested presets so effects work correctly on the first attempt. ## Core Features & Use Cases - Complete ParticleSystem reference: Every field documented with types, defaults, and behavioral rules, including blend modes, simulation space, sprite sheets, and playback control. - 17 production-ready presets: Fire Ember, Magic Aura, Snowfall, Heavy Rain, Fireworks Loop, One-Shot Burst, Asteroid Trail, Campfire, and more, ported from the official SDK7 test scenes. - Creator Hub integration guidance: When to tune particles in the editor inspector versus driving them from code at runtime. - Use Case: Add a looping fireworks display to a Decentraland scene by attaching a ParticleSystem with staggered bursts, PSB_ADD blending, and a cone shape, using preset 14 as the starting configuration. ## Quick Start Add a looping fire ember particle effect to the entity at position 8,1,8 in my Decentraland SDK7 scene.
