Gmod Light / Environment Editor

Description
- About This Addon -

To put it simply, this addon is meant to allow you to mess with the lighting of maps mid-game, while also reducing the negative side effects of doing so as much as possible.

If you need one, the first video on the workshop page is a quick tutorial on how to use this. (Though it is currently outdated, and a lot of things have been improved or added since then.)


- Extra Details -

This addon has the most functionality on maps with named light_environments, as this separates ambient light and sunlight (allowing you to adjust both separately). The rest of the addon works more-or-less the same with/without one, though you may need a different combination of work-arounds as the lighting behaves slightly differently in both contexts.

Since neither source nor gmod were designed to accommodate what this addon does, there's a lot of weird jank and a few unfixable issues. Nothing this addon does will persist beyond a restart. You may encounter entities that don't update their lighting with the ambient light slider. There's usually nothing that can be done about this, and there are a number of buttons to outright remove these for that reason. Wherever there are seemingly arbitrary limitations (e.g. the 1-26 range for light level) these are usually for technical reasons and can't be changed.

This addon may very rarely cause lamps/lights to not work properly at all, in which-case you can disable the lamp/light fixer to make them work normally again.

The "Skybox Texture" box directly changes sv_skyname, you can find the skybox names for most games by just searching for them on your preferred search engine; But to save you the trouble: Here's the list of skyboxes for half-life 2

- Console commands -

  • Environment_ambientLightLevel (1-26)
    - Controls light in shadows and from artificial sources, 12 is default, 1 is pitch black.

  • Environment_SunLightLevel (1-26)
    - Controls direct light from the sun, 12 is default, 1 is pitch black

  • Environment_ChangeLightStyle (0-1)
    - Whether or not the fix for lamps/lights is activated

  • Environment_ForceDisabledSkybox (0-1)
    - Sets r_3dky to 0 for all players

  • Environment_ForceDisabledCubemaps (0-1)
    - Sets mat_specular to 0 for all players

  • Environment_ForceRadiosityZero (0-1)
    - Sets r_radiosity to 0 for all players (which helps in outdoor areas and with static/dynamic props still being lit)

  • Environment_DarkenWater (0-1)
    - Darkens the colour of water fog based on the current value of Environment_ambientLightLevel to fix water sources appearing glow-y.

  • Environment_DarkenRopes (0-1)
    - Sets the colour of any ropes that were part of the map to black

(The commands in this table remove all of a certain entity type from the map)

  • Environment_stopSoundscape
    - Runs stopsound and stopsoundscape for all players. Requires sv_cheats 1 to work properly.

  • Environment_DisableStaticAmbientLighting
    - Uses black-magic to disable the map lighting on static props entirely. This will last until you start a new game/restart the server, so only use it if you're planning to keep the map pitch-black for the entire session.

  • Environment_DisableStaticSelfIllum
    - Disable self-illumination on all static props. This one can be toggled on/off. This is useful for any lamp props that are part of the map, as otherwise they'll be fully-bright/glowing.

    *Note: This edits the material rather than the static prop itself, so props with the same material as a static prop on the map will also have no self-illumination while this is turned on.

If you wish to contribute, a github repository for this is available here[github.com]
There's also a channel set up for this addon in the Octantis Addons Discord[discord.gg].

Nothing I can do about that, sorry. Some addons essentially un-do the work-around this mod uses when setting up their lights. I physically can't stop them from doing that. "Advanced Light Entities" also has this issue (or at least it did last time I tested, which was a few years ago).

Doesnt work with jmod properly, when I use the flare/glowstick theres no light but when i put ambient light to 2 it works fix it so it will work with ambient light on 1

thx
JonahSoldier  [author] 19 Aug @ 11:54am 
That's a bit vague, but that can probably either be fixed by turning on the option to force mat_specular 0 for all players, or by turning on the option to force r_radiosity to 0 for all players.

My friends' stuff is glowing. is there any way to fix this? If anything, I'm the host

oh, I thought that was something that could be done in the Light/Environment editor, Not the Sky editor.
JonahSoldier  [author] 7 Aug @ 9:14am 
Set the sky name to "painted" and then use the sky editor that exists in vanilla gmod.

How come you can Blackout the Sky while I can't!?

The first video on the workshop page's a tutorial. I can't make it any simpler without taking control away from people.
