env_skypaint

env_skypaint is a point entity available in Garry's Mod.

env_skypaint
Type	Point entity
Engine	Source
Availability	Garry's Mod

It allows the creation of custom dynamic skyboxes (Both HDR and LDR). It can be overridden by the Sky Editor (edit_sky) entity spawned by the player in game.

gm_construct uses env_skypaint

gm_flatgrass also uses env_skypaint

Important:The name of the skybox must be painted in order for this entity to work

Note:The colors are in color1 format instead of color255. In order to convert color255 to color1, divide each value by 255 (ex: 200/255=0.78).

Sky creation

1. Place env_skypaint somewhere in your map.
2. Change sky name to painted.
3. Compile and run map.
4. Using the spawnmenu, spawn the Sky Editor entity somewhere in your map (in the Entities tab under "Editors").
5. Go to entity's properties and edit the values as you wish.
6. When your're done, copy the values to your env_skypaint.
7. Compile the map again. DONE

Name (targetname) <string>

Entity's name

Sky Top Color (topcolor) <color1>

The colour of the top of the sky

Sky Bottom Color (bottomcolor) <color1>

The colour of the bottom of the sky

Sky Fade Bias (fadebias) <float>

Controls the bias of the fade between top/bottom (1.0 is even)

Sun Size (sunsize) <float>

Controls the size of the sun glow

Warning:not to be confused with env_sun

Sun Normal (sunnormal) <vector>

The position of the sun, expressed as a normal from the center of the world

Sun Position Method (sunposmethod) <choices>

How should we determine the position of the sun?

• 0: Custom - Use the Sun Normal to position the sun
• 1: Automatic - Find a env_sun entity and use that (Uses env_sun values)

Sun Color (suncolor) <color1>

The color of the sun glow (this is additive)

Dusk Scale (duskscale) <float>

The size of the dusk effect (colouring of the horizon)

Dusk Intensity (duskintensity) <float>

How powerful the dusk effect is

Dusk Color (duskcolor) <color1>

The color of the dusk effect

Draw Stars (drawstars) <choices>

Draws a specified texture as an overlay

• 0: No - Don't draw stars
• 1: Yes - Draw the stars please

Note:Drawn using additive translucency.

Stars Texture (starstexture) <string>

The star texture

Stars Scale (starsscale) <float>

How big the star texture should be

Star Fade (starsfade) <float>

Fade the star texture towards the horizon

Stars Speed (starsspeed) <float>

How fast the star texture should scroll across the sky

HDR Scale (hdrscale) <float>

When rendering your skybox in HDR mode, output will be scaled by this amount

Inputs

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 <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>

FireUser1 to FireUser4

Causes this entity's OnUser output to be fired.

Outputs

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.
