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 (Though it is currently outdated, and a lot of things have been improved or added since then.)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].

Set the sky name to "painted" and then use the sky editor that exists in vanilla gmod.

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

@Raptor Jesus I've added a workaround to let superAdmins edit this addon's cvars. I also ran into a few other issues that I hadn't detected before (and that for some reason no one has reported), because I've previously only been testing in p2p/singleplayer. I've fixed most of those, though the 2 options at the bottom of the menu (disableStaticSelfIllum & disableStaticAmbLight) currently still only work in singleplayer. I'll get around to fixing those too at some point, but I've updated the addon with the current changes in the meantime.

my issue is that i can't seem to change the skybox at any level of permission in this case.
Raptor Jesus Jul 7 @ 6:05am 
can you make a permissions/access change so that this can be used by admins on dedicated servers? thank you, this addon works great besides this!
