Clouds & ambient particles

Cloud drift and ambient particles are separate controllers with their own art, references and ownership. Configure each before applying weather changes.

Clouds#

1. Enable Clouds and assign a cloud Sprite.
2. Verify the Layer reference, factor/order and optional Horizontal looping.
3. For the guide's horizontal example, set Velocity (0.25,0) and Opacity 0.8; the supplied screenshot uses its own authored direction.
4. Assign Day/Night colors and Clock. Cloud velocity adds drift to Camera Driven motion.

Positive cloud X drift moves right. Manager's positive auto-scroll X convention moves scenery left, so these are different controls. Use Add Another Clouds for independent art/speed/opacity.

Optional cloud shadow#

Shadow needs a separately authored transparent SpriteRenderer; assigning a reference does not create geometry. Shadow Offset adjusts its authored local position, while Shadow Opacity is a daytime multiplier fading at night.

An enabled cloud controller owns layer.tint, capturing the original and applying day/night color × opacity. A transition/gameplay writer can conflict with it. Shadows are a visual approximation. Test stationary-camera drift, looping and longer travel.

Particle styles#

1. Enable Particles and verify Advanced > System.
2. Select Fireflies, Leaves, Dust or Floating, then click Apply Particle Style.
3. Set desired Emission Rate afterward; guide example eight particles/s is before quality/night multipliers.
4. For Fireflies, test Night Only with a valid clock at Hour zero.
5. Author renderer material, alpha, sorting, shape and scale. Add Another Particles creates another independent effect.

Reapplying a style may overwrite tuned modules. Retune desired values after Configure. Simulation is world-space, so existing particles stay in world coordinates even when the emitter follows the camera.
