The World module controls global lighting, atmospheric effects, volumetric clouds, and gas simulations.

1. Nishita Sky Model

Please save a screenshot of the Sky Settings Panel as docs/images/world_sky.jpg

Physically based spectral sky model simulating Rayleigh and Mie scattering.

Parameter	Description
Sun Elevation	Height of the sun (Day/Night cycle).
Air Density	Controls Rayleigh scattering (Blue/Red sky).
Dust Density	Controls Mie scattering (Haze/Pollution).
Ozone Density	Absorption filter for deep blue zenith.
Sun Intensity	Brightness multiplier.

Please save a screenshot of the Cloud Settings Panel as docs/images/world_clouds.jpg

Ray-marched volumetric clouds with multi-scattering approximation.

Parameter	Description
Coverage	Amount of clouds (0.0=Clear, 1.0=Storm).
Density	Thickness of the cloud layer.
Absorption	Light absorption inside clouds (Silver lining).
Detail Scale	Frequency of the noise texture.
Wind Speed	Movement speed across the sky.

Please save a screenshot of the Gas Simulation Panel as docs/images/world_gas.jpg

A powerful GPU-accelerated fluid solver for smoke, fire, and explosions.

Parameter	Description
Grid Size	Physical world dimensions of the simulation box.
Buoyancy	Upward force based on temperature (Hot smoke rises).
Vorticity	Injects small swirling details to prevent diffusion.
Dissipation	Rate at which smoke/temperature fades over time.

Parameter	Description
Scattering	Dual-Lobe Henyey-Greenstein phase function.
Multi-Scatter	Approximates internal light bounces for realism.
Blackbody	Emits light based on physical temperature (Fire).

Please save a screenshot of the Force Field Settings Panel as docs/images/world_forces.jpg

Invisible forces that manipulate the motion of Gas and Smoke simulations.

Type	Description
Point Force	Radial force. Positive pushes out (Explosion), Negative pulls in (Implosion).
Directional	Uniform force in a specific vector direction (Wind).
Vortex	Rotational force around a central axis (Tornado).
Turbulence	Adds curl noise to break up uniform motion and add chaos.
Drag	Resistance force that slows down fluid velocity over time.

Parameter	Description
Strength	Magnitude of the force.
Radius	Effective range of the force field.
Falloff	How quickly the force weakens from the center.
Position	3D World coordinate of the force center.
