{{wrongtitle|title=light_environment}} {{base_point}} ==Entity Description== [[Image:light_environment.png|left]] The '''light_environment''' entity is a light controller, that casts both diffuse and parallel directional lighting from the [[tool textures|toolsskybox]] texture. This is to approximate the light cast from the Sun or Moon. * {{map_properties}} A [[3D Skybox]] does ''not'' require an extra light_environment placement. If multiple light_environment entities are placed, [[Vrad]] uses the keyvalues from the first placed light_environment to calculate the lighting. {{clr}} {{skybox_lighting}} ==Keyvalues== * {{KV Angles}} : This is the angle at which the ''Direct'' Sunlight enters the map through each [[toolsskybox]] brush. : ''Tip:'' Pitch is the Sun's Angle of Elevation from the ground, and Yaw is its Compass Bearing. * '''_light''' {{color}} <[[integer]]> : Brightness : The RGB color followed by the Brightness of ''Direct'' Sunlight. * '''_ambient''' {{color}} <[[integer]]> : Ambient : The RGB color followed by the Brightness of ''Diffuse'' Skylight. * '''_lightHDR''' {{color}} <[[integer]]> : BrightnessHDR : This approximates ''Direct'' [[HDR]] sunlight. Can be left as default or be slightly less bright, since HDR is sometimes rendered brighter. * '''_lightscaleHDR''' <float> : BrightnessScaleHDR : Amount to scale the ''Direct'' light by when compiling for HDR. * '''_ambientHDR''' {{color}} <[[integer]]> : AmbientHDR : This is the ''Diffuse'' [[HDR]] light. Can be left as default or be slightly less bright. * '''_AmbientScaleHDR''' <float> : AmbientScaleHDR: Amount to scale the ''Diffuse'' light by when compiling for HDR. * '''pitch''' <angle> : Pitch : This value overrides the value of pitch in the keyvalue "angles". 90 is straight up, -90 is straight down. {{warning|Unfortunately Valve introduced a ''Pitch override'' parameter to the [[light_environment]] and [[env_sun]] entities, but not to [[shadow_control]]. Even more unfortunately, the ''Pitch override'' cannot be switched off and its rotation is measured counter-clockwise from the horizontal (so straight down is -90&deg;) whereas the ''<angles> Pitch'' is rotation is clockwise (so straight down is +90&deg;). The workaround for this is to make sure your ''Pitch override'' merely repeats the ''<angles>'' value; for example, if your [[shadow_control]], [[light_environment]] and [[env_sun]] ''<angles>'' are "45 -60 0" set the ''Pitch override'' to "-45".}} * '''{{EP2 add|SunSpreadAngle}}''' <float> : SunSpreadAngle : The angular extent of the sun for casting soft shadows. Higher numbers are more diffuse. 5 is a good starting value for just nice blurriness. Remember: on cloudy days, the shadows will be blurred because the sunlight is being diffused by clouds. Try 90 for hazy days, and use 135 for cloudy days, rain and fog. If you're trying a night atmosphere, sometimes you'll need up to 180. You'll also have to turn down the shadow alpha in your [[shadow_control]] entity - try changing the Shadow Color variable to something such as 50 50 50.
