Stone Skin Buff

HOW IT'S MADE

Stone Skin Buff stacks 9 particle emitters, each with its own job. Techniques worth a look: glowing strokes traced along shapes, magnets, sub-emitters set off by other particles, collisions and post filters (bloom and vignette). A scene layer (ground or a prop) shows in the studio for context and stays out of every export.

It loops seamlessly every 2.4 s, and one layer fires in bursts, so it pulses instead of flowing evenly. To change its colour, select "Harden Flash" in the studio and edit Colour A and Colour B. Size on the same layer sets how big its particles are. The colour swatches by the downloads recolour every layer at once.

Layers, in draw order

1. Ground CracksparticlesA single long-lived particle that stays for the whole loop.
2. Crack Glow, Seam Glowparticles / additiveA single long-lived particle that stays for the whole loop.
3. Flung RocksparticlesA stream of debris from a ring, its rate keyframed over the loop. They set off "Impact Dust" on impact, are pulled toward a magnet, fall under gravity and stick where they land. Colour runs from white to orange over each life.
4. Impact DustparticlesSmoke puffs set off by "Flung Rocks". They grow as they age and slow down with drag. Colour: orange.
5. Stone PlatesparticlesA stream of debris across a box, its rate keyframed over the loop. They swell and then shrink away. Colours range between grey and dark grey.
6. Hardening Rimstroke / additiveA glowing line traced along the outline of a sprite.
7. Harden Flashparticles / additiveA single particle at 0.72 s. Colour: orange.
8. Amber Glintsparticles / additiveA stream of image sprites around a box outline, its rate keyframed over the loop. They swell and then shrink away. Colours range between pale gold and orange.
9. Crumble DustparticlesA stream of smoke puffs across a box, its rate keyframed over the loop. They fall under gravity and grow as they age. Colour: orange.
