Twenty drop-in smoke, steam and fog effects built as real Unity ParticleSystem prefabs. Drag one into your scene and it runs. No sprite sheets, no frame sequences, and nothing to wire up.

WHAT YOU GET

Chimney Smoke, Steam Vent, Campfire Smoke, Dust Puff, Fog Bank, Poison Cloud, Smoke Bomb, Exhaust Plume, Geyser Steam, Ash Fall, Toxic Vent, Drifting Mist, Sand Drift, Smoldering Smoke, Cannon Smoke, Sewer Steam, Incense Smoke, Dust Devil, Cloud Puff, Ground Fog.

These are not recolours of one effect. Incense is a three degree cone of thin wisps at twelve particles a second; Ground Fog is an eighty degree spread of two and a half metre puffs that barely move. Each is built from its own emission rate, size, drift and colour ramp.

BUILT TO BE EDITED

Everything worth changing sits on the ParticleSystem itself, where you already know how to find it. Colour Over Lifetime holds the gradient, Start Size and Start Speed set the scale of the motion, Emission sets the density, and the Noise module sets how much the plume wanders. Because these are particle systems and not baked frames, they scale, tint and re-time without anything being redrawn.

LIGHT ON YOUR PROJECT

The whole pack draws from two small greyscale masks: 128x128, twice, for all twenty effects. A flipbook pack of the same size costs you megabytes of atlas.

DEMO SCENE INCLUDED

A demo scene lays out all twenty on a ground plane with their names beside them. Open it, press Play, and copy what you want straight into your own project.

TECHNICAL

Unity 2021.3 or newer, built-in render pipeline.

URP and HDRP: switch the two materials to Universal Render Pipeline/Particles/Unlit with Additive and Alpha blending. The prefabs, curves and gradients are pipeline independent.

20 prefabs, 2 materials, 2 textures, 1 demo scene.

Every effect loops and runs until the object is disabled.

Authored for a two metre humanoid; scale the transform to resize.
