A complete environmental VFX library for Unreal Engine, authored entirely in Niagara. 39 unique effects span weather, tornadoes, fire, water, smoke, falling foliage and wildlife, backed by screen-space post-process effects for the moments the camera itself should react.

Every system is self-contained and drag-and-drop. Pull one into your level, scale it to your scene, and it runs - no blueprint wiring, no dependency chain, no plugins. Emitters are authored on both CPU and GPU simulation, so dense effects push particle counts on the GPU while lightweight ones stay cheap on the CPU.

Effects are built to layer. Stack rain, mist and a storm cloud for a downpour; add thunder strikes and a thunder tornado for the moment the weather turns. Each system exposes its user parameters, so intensity, colour, scale and lifetime are tunable per-instance without duplicating assets.

Preview

• Heavy Rain — full-scene rainfall with surface impacts

• Snow Smoke — drifting snowfall for blizzard and light-flurry conditions

• Cloud & Thunder — volumetric storm cell with internal lightning flashes

• Thunder Strike — ground-strike lightning bolt with impact burst

• Mist — low-lying ground fog and rolling haze

• Sand Tornado — desert funnel with airborne grit and debris

• Fire Tornado — burning vortex with embers and a rising smoke column

• Thunder Tornado — storm funnel charged with arcing lightning

• Grass Fire — spreading low flame for open ground

• Wood Fire — campfire and torch-scale flame

• Explosion Fire — burst ignition with rolling smoke

• Flame Dust — floating embers and ash drift

• Smoke Spark — sparks with trailing smoke

• Smoke Stream — continuous smoke column for chimneys and wreckage

• Dust Drain — falling dust and fine particulate

• Dust & Leaf Vortex — swirling wind pocket that lifts dust and leaves

• Water Stream — pressurised jet with spray breakup

• Water Drop — dripping and falling droplets

• Water Drain — sheeting run-off and drainage flow

• Leaves Fall — autumn leaf drift

• Leaves Blow — wind-driven leaves across the ground plane

• Dandelion — floating seed heads

• Butterfly 3D — mesh-based butterflies with flight behaviour

• Butterfly 2D — lightweight sprite butterflies for distance and density

• Firefly — glowing insect swarm for night scenes

• Screen Freeze — post-process ice build-up on the camera

• Screen Rain Drop — rain-on-lens post-process with running droplets

• Rainbow — rainbow material and mesh for post-storm skies

• DemoLevel — a showcase room where every effect plays on its own numbered pedestal, so you can audition the whole library in one pass

• LandscapesDemoLevel — the same effects staged in full environments: desert, snowfield, jungle and meadow, showing how they read at scene scale

• Drag-and-drop systems with exposed user parameters — no setup required

• CPU and GPU emitters, chosen per effect for cost

• No third-party plugins or external dependencies

• Windows and Mac supported
