Particle Presets

Fine motes suspended through a large volume of air, drifting on a faint sideways wind and swirling on low-amplitude turbulence. Emitted through a box of half-extents 320 × 200 × 320 at 34 particles/second, 6–12 s lifetime, 2–5 pt, warm off-white at 35% alpha, 700 particles maximum, 8 s warm-up. Soft sprites.

A few very large, very faint sprites drifting sideways, overlapping into a haze rather than reading as particles. Box of half-extents 520 × 120 × 520, 12 particles/second, 10–16 s lifetime, 220–360 pt, near-grey at 12% alpha, 220 particles maximum, 12 s warm-up. Wind 20 at strength 0.4 and very slow, very low turbulence.

Gravity 1200 down. Rendered as velocity-stretched streaks. A horizontal collision plane, 400 points down, kills each drop on impact and spawns 3–6 splash particles.

Leaves shed from a wide box overhead, tumbling hard on strong turbulence and darkening as they fall. 18 particles/second, 6–11 s lifetime, 14–30 pt, spinning at ±3.5 rad/s, a five-swatch autumn palette with 30% colour jitter, 600 particles maximum, 4 s warm-up. Gravity 52 down, drag 1.0, wind 26, turbulence amplitude 105. Rendered as leaf meshes.

Petals drifting down, lighter and slower than the leaves, on stronger and finer turbulence. 24 particles/second, 7–12 s lifetime, 9–17 pt, spinning at ±2.5 rad/s, a three-swatch pink palette, 600 particles maximum, 4 s warm-up.

A cone of flame lifting and thinning, its colour running a five-stop ramp from white through yellow and orange to a dark red that fades to nothing. Cone of half-angle 0.4 rad and radius 30, 260 particles/second, 0.45–1.0 s lifetime, 60–150 pt/s, 30–62 pt, 1600 particles maximum. Gravity 280 up, drag 1.6, turbulence amplitude 200 over three octaves evolving at 1.5 — the fastest-evolving turbulence of any preset. Size peaks at a third of life then collapses to 0.12.

A slow column billowing upward, growing to six times its birth size and lightening from charcoal to pale grey. Cone of half-angle 0.35 rad and radius 40, 62 particles/second, 2.2–5.5 s lifetime, 30–72 pt/s, 55–115 pt, 900 particles maximum. Gravity 72 up, drag 0.55, turbulence amplitude 110 over four octaves — the only preset with four. Size runs 0.4 to 2.4 over life.

Sparse orange motes lifting from a fire and flickering out, cooling from bright orange to deep red.

A four-point flicker curve drives alpha. Short streaks.

Fast, tiny, ballistic streaks thrown from a narrow point and falling away hot-white to red. Cone of half-angle 0.6 rad and radius 5, 200 particles/second, 0.3–0.8 s lifetime, 150–350 pt/s, 3–6 pt, 1000 particles maximum. Gravity 500 down, drag 0.5, turbulence 40 over a single octave. Streaks.

A single non-looping blast: 70 particles released at once from a small sphere, swelling and fading to transparent while each one trails sparks and leaves smoke behind. 0.3–0.6 s lifetime, 200–500 pt/s, 40–90 pt, 200 particles maximum, gravity 150 down, drag 2. Size peaks at 1.4× a fifth of the way through life. Every particle spawns two sparks at birth and one smoke puff at death.

Rockets that climb and burst. A single rocket is launched every 0.7 s, four times over, at 580–660 pt/s against gravity 300 down, and lives 1.1–1.35 s before dying at the top of its arc. Each death releases 80–120 sparks and one bright flash; each spark, when it dies, releases 2–4 crackles. Twelve rockets maximum. Rendered as a streak.

160 paper rectangles released in a single burst from a wide cone, spinning hard and fluttering down through turbulence. 2–5 s lifetime, 250–520 pt/s at spread 0.5, 10–18 pt, spinning at ±8 rad/s, a six-swatch party palette, 1000 particles maximum.

Streaks. A horizontal collision plane, 300 points down, with slight bounce and friction, kills each droplet and spawns 2–4 splash particles.

Gravity 700 down, drag 0.05. Streaks. A horizontal collision plane, 500 points down, kills each particle and spawns 2–5 splash particles.

Gravity 30 up, drag 0.8, turbulence 60. Star sprites.

Size grows then shrinks, and a four-point twinkle curve drives alpha. Star sprites.

Particles orbiting a ring and pulled towards its centre, forming a spinning disc. Circle emitter of radius 100 and thickness 0.3 — an annulus, not a disc — 220 particles/second, 1–2 s lifetime, 8–16 pt, three violet and blue swatches, 1500 particles maximum. A vortex of strength 4000 about the Z axis, an attractor of strength 200 with a 40-point softening radius, and drag 0.5.

A wide, slow spiral of small stars. Circle emitter of radius 260, 120 particles/second, 3–6 s lifetime, 1–8 pt/s, 3–8 pt, four pale swatches, 2000 particles maximum, 3 s warm-up.
