env_skypaint is a point entity available in Garry's Mod (Since GMod 13). It allows to create custom dynamic skybox (Both HDR and LDR).

gm_construct uses env_skypaint

gm_flatgrass also uses env_skypaint

It can be overridden by Sky Editor (edit_sky) entity spawned by player in game.

Note:Set skybox name to painted to get this entity to work.

Note:The colors aren't in RGB "255 255 255" format. In order to convert them to these values, you'll need to get your color value (such as 200 and divide it like 255/200, resulting in 0.78 rounded for the red color field)

Note:Since env_skypaint isn't related to VRAD at all, you'll need to make your own light_environment for your skybox inside Hammer.

Sky creation

1. Place env_skypaint somewhere in your map
2. Change sky name to painted
3. Compile and run map
4. Using a Q menu, spawn the Sky Editor somewhere in your map.
5. Go to sky editor properties and edit the values as you wish.
6. When your done, just copy values to env_skypaint
7. Compile map again. DONE

Input

Kill

Removes this entity from the world.

KillHierarchy

Removes this entity and its children from the world.

Note:Entities already remove orphaned children upon being removed, but this input removes all children on the same frame, being marginally faster than Kill.

AddOutput <stringRedirectInput/string>

Adds a keyvalue/output to this entity. It can be potentially very dangerous, use with care.
KV Format: <key> <value>
I/O Format: <output name> <targetname>:<inputname>:<parameter>:<delay>:<max times to fire, -1 means infinite>

Output

OnUser1 to OnUser4

These outputs each fire in response to the firing of the like-numbered FireUser1 to FireUser4 Input; see User Inputs and Outputs.
