env_skypaint

env_skypaint is a logical entity available in 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

Draw Stars (drawstars) <choices>

Whether to draw the star/cloud texture at all.

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.

Star Layers (starlayers) <float>

From 1 to 3, how many layers should the star texture be repeated over.

HDR Scale (hdrscale) <float>

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