| [[Image:Toolsskybox.gif|right]][[Template:skybox lighting|Skybox Lighting]] enters the map through every [[skybox|toolsskybox]]-textured [[brush]], representing direct sun/moonlight and diffuse skylight. Its basic properties are controlled by three entities used in combination (four in some games): | | [[File:Toolsskybox.gif|right]] |
| | | {{Multipage|Skybox lighting}} |
| * {{ent|light_environment}} defines the direction, color and intensity of the direct sunlight, and the color and intensity of the diffuse skylight.
| | [[Category:Lighting]] |
| * {{ent|shadow_control}} defines the color, direction, and attenuation distance of the [[Dynamic Shadows|dynamic shadows]] that are created by <code>light_environment</code>. Dynamic shadows will be buggy and unconfigurable without this entity.
| |
| * {{ent|env_sun}} places a glowing sprite in the skybox to represent the Sun's apparent position in the sky. It has no effect on lighting aside from this.
| |
| * {{ent|env_cascade_light}} casts harsh, real-time shadows onto the map, usually copying settings from the {{ent|light_environment}} entity. {{since|{{csgo}}}}{{also|{{bms}}}}

| To make sense of it all, just make sure you have only one of each of these entities in your map, and that the '''Pitch and Yaw <angles>''' are set the same for all three of them. (''Pitch'' is equivalent to the Sun's angle of elevation from the ground, and ''Yaw'' is its compass bearing.)

| These lighting settings—direction, color, brightness, etc.—are fairly specific to the actual image used for the 2D skybox. The [[Sky List]] article suggests some settings for official game skyboxes. The {{ent|worldspawn}} entity defines which [[Sky List|skybox]] to use. Also note that fog will look wrong if {{ent|env_fog_controller}}'s settings don't correspond to the particular skybox in use.

| {{Note|'''Pitch''' can be overridden for <code>light_environment</code> and <code>env_sun</code>, but not <code>shadow_control</code>. The '''Pitch''' override also cannot be switched off and its rotation is measured counter-clockwise from the horizontal (so straight down is -90°) whereas the '''<angles> Pitch''''s rotation is clockwise (so straight down is +90°). The workaround for this is to make sure your '''Pitch''' override merely repeats the '''<angles>''' value; for example, if your <code>shadow_control</code>, <code>light_environment</code> and <code>env_sun</code> '''<angles>''' are "45 -60 0", set the '''Pitch''' override to "-45".}}{{clr}}
