Overview

Weather particles add atmospheric particle effects to the scene to simulate environmental conditions such as rain, snow, or falling leaves. Built-in presets are available: Off, Dust, Rain, Snow, Petal, Leaf, Glitter.

Particle settings

Spawn Rate (0–2): Controls the density of particles. Higher values produce more particles.
Gravity: Controls how strongly particles fall. Negative values cause particles to fall downward.
Velocity: Sets the initial velocity of particles when spawned.
Turbulence: Applies random movement to particles, creating a more natural appearance.
Drag: Air resistance applied to particles, slowing them as they travel.
Bounce: Controls how much particles bounce when they hit the ground or scene objects.
Spin: Rotation speed of individual particles.
Collision: When enabled, particles collide with scene objects rather than passing through them.
Spawn from top: When enabled, particles spawn from the top of the spawn area. When disabled, particles spawn randomly throughout the volume.
Texture: Selects the particle texture or type to use.
Size: Controls the size of each particle.
Lifetime: Sets how long each particle remains visible before disappearing.
Height: Sets the height of the particle spawn area.
Stay on Ground (0+): How long particles remain on the ground after landing. A value of 0 causes them to disappear on contact.

Rain shader

The rain shader applies a screen-space effect that simulates rain droplets forming on the camera lens, adding an extra layer of immersion during rain weather.

Audio

Controls the volume of weather audio, such as rain sounds or ambient environmental noise.
