Env sun

Entity description

Places a sun effect (glow sprite) in the skybox representing the Sun or Moon. It does not contribute any actual lighting - this entity is best used in conjunction with a light_environment.

• The effect's position relative to the player is determined by angle; it does not parallax, so gives the effect of the sun being infinitely far away.
• You can also send inputs to the env_sun entity by directing them to "env_sun" instead of using a target name.
• The effect is additive with the sky: a pure yellow sun with a bright blue sky will appear white in-game; change the color to account for this.

Warning:light_environment, env_sun and shadow_control should be used together. Each entity represents only a one aspect of a naturally unified phenomenon; Sunlight. light_environment defines the direct sunlight settings and creates (buggy, unconfigurable) dynamic shadows which can only be overridden/controlled by shadow_control. env_sun places a glow sprite in the skybox where the sunlight comes from. To make sense of it all, just make sure that the <angles> (Pitch/Yaw/Roll) are set the same for all three entities. Unfortunately shadow_control does not have the Pitch override parameter, so its Pitch will be determined by the first of its <angles>. Even more unfortunately, the Pitch override rotation cannot be switched off and is measured counter-clockwise from the horizontal (so straight down is -90 degrees) whereas the <angles> Pitch is rotation is clockwise (so straight down is +90 degrees).

Keyvalues

• Template:Not in fgd Template:Kv targetname
• Template:Kv angles
• target

<target_destination> Name of an entity used to determine where the sun is in the skybox. The sun should be lined up on a line from this entity to the env_sun entity.

• Template:Kv hdrcolorscale
• use_angles

<boolean> The old way to orient env_sun is to point it at a target. The new way is to specify the angles. If you use the new way, set this property to YES, otherwise, set this property to NO.

• pitch

<integer> The pitch of this entity. 90 is straight up, -90 is straight down.

• rendercolor

⇆#000000rgb(0,0,0)⇆ Color of the sun.

• size

<integer> Size of the sun.

• Template:Ep1 add

⇆#000000rgb(0,0,0)⇆ Overlay Color (R G B)

A value of 0 0 0 will act the old way.

• Template:Ep1 add

<integer> Overlay Size

A value of -1 means the overlay will act the old way.

• Template:Ep1 add

<material> Material Name

Material of the inner glow. (sprites/light_glow02_add_noz)

• Template:Ep1 add

<material> Overlay Material Name

Material of the overlay glow. (sprites/light_glow02_add_noz)
