Constants

Sun, moon and stars

Constant	Type	Value	Description
SKY_SUN	integer	14	Environmental sun parameters: rotation, scale, color, is_default_texture, direction vector, ambient color, and diffuse color.
SKY_MOON	integer	9	Environmental moon parameters: rotation, scale, brightness, is_default_texture, direction vector, ambient color, and diffuse color.
SKY_SUN_TEXTURE	integer	21	Environmental setting containing the inventory name or UUID of the texture used for the sun.
SKY_MOON_TEXTURE	integer	20	Environmental setting containing the inventory name or UUID of the texture used for the moon.
SKY_GLOW	integer	6	Environmental setting for sun and moon glow parameters: size and focus.
SKY_STAR_BRIGHTNESS	integer	13	Environmental setting for the brightness value applied to stars.

Sky colour and atmosphere

Constant	Type	Value	Description
SKY_AMBIENT	integer	0	Environmental setting for the ambient color used in the scene.
SKY_BLUE	integer	22	Environmental setting containing the colors used to calculate blue density and blue horizon in the sky.
SKY_HAZE	integer	23	Environmental setting containing the values used to calculate the light scattering impact of blue density and blue horizon on the scene.
SKY_GAMMA	integer	5	Environmental setting for the gamma value applied to the scene (repurposed in viewer 7.0+ as the HDR Scale value in the EEP editor).
SKY_DOME	integer	4	Environmental setting containing sky dome parameters: offset, radius, and maximum altitude.
SKY_PLANET	integer	10	Environmental planet rendering parameters: planet_radius, sky_bottom_radius, and sky_top_radius.
SKY_REFRACTION	integer	11	Environmental sky refraction parameters for rainbows and optical effects: moisture_level, droplet_radius, and ice_level.
SKY_REFLECTION_PROBE_AMBIANCE	integer	24	Environmental setting for the minimum ambiance value of all reflection probes. Note: Supported in the GLTF Materials project, requiring compatible viewers and testing areas.

Clouds

Constant	Type	Value	Description
SKY_CLOUDS	integer	2	Environmental cloud parameters including color, coverage percentage, scale, variance, scroll speed (X/Y), density, detail exponents, and default texture status.
SKY_CLOUD_TEXTURE	integer	19	Environmental setting containing the inventory name or UUID of the texture used for the clouds.

Water

Constant	Type	Value	Description
WATER_FOG	integer	101	Environmental underwater fog parameters: color, density exponent, and modulation.
WATER_NORMAL_TEXTURE	integer	107	Environmental setting containing the inventory name or UUID of the normal map texture used for water waves.
WATER_NORMAL_SCALE	integer	104	Environmental setting specifying the scaling vector applied to the water normal map.
WATER_WAVE_DIRECTION	integer	106	Environmental wave direction vectors (X is east/west, Y is north/south) specifying speeds and directions for both large and small waves.
WATER_FRESNEL	integer	102	Environmental water surface Fresnel scattering parameters: offset and scale.
WATER_REFRACTION	integer	105	Environmental water surface refraction scale factors: scale_above and scale_below.
WATER_BLUR_MULTIPLIER	integer	100	Environmental setting specifying the multiplier applied to blur the scene when underwater.

Used by

• llSetAgentEnvironmentfunctionSets an individual agent's environmental settings using the attributes in params over a duration of transition seconds. Must be used as part of an experience; passing an empty list removes overrides.
• llSetEnvironmentfunctionOverrides the environmental settings at position for a parcel (or region if position is <-1.0, -1.0, z>) using the parameters in params. Passing an empty params list removes previous overrides.
