env_skypaint is a logical entity available in Garry's Mod 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
Icon-Important.pngImportant:The name of the skybox must be painted in order for this entity to work
Note.pngNote: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

Keyvalues

Name (targetname) <string>[ Edit ]
The name that other entities refer to this entity by, via Inputs/Outputs or other keyvalues (e.g. parentname or target).
Also displayed in Hammer's 2D views and Entity Report.

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.pngWarning: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.pngNote: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
