Hammer Editor - Make the Map darker after specific time

[opti2000]

Hello my friends its me again

I am just wondering if its possible to make the map darker after a specific time?

For Example:

Map is for 10 minutes bright and gets then slowly darker and darker for 10 minutes and gets again brighter slowly.

Hope there are some possibilities for that

You can sort of fake it with a custom skybox (using a 3d model instead of the 2d bruszhes).

Unfortunately my google skills are not up to what they used to be. Maybe you have some better look than me. (Check gamebanana.com

Talking about sunlight, nope. Source's lighting is precomputed lightmaps. The only lighting that can change are localized light sources from the light, light_spot, light_dynamic, and projected_texture entities, and even then there are limitations to that.

Giving light_env a targrtname lets you control it like a normal light. But it makes it look lower quality.

You can probably fake it with colour correction

This is the best option, you could also fade in some clouds in a 3D skybox too if needed.

I would also try using an env_tonemap_controller.

But the shadows won't shift ... so I guess I would just give up on the idea and think of something else.

If you really want to do proper outdoor lighting, thanks to the way Source's lighting is built (on the back of a 1999 engine booted up to 2003, then 2007) lighting is static.

The only way to achieve sunlight is through something similar to CSGO's system, with pre-baked ambient occlusion and a sunlight entity somehow attached to a mobile system, but I wouldn't want to be the guy coding that. GMod managed it with Lua though, so it's not impossible - but it sure as hell isn't easy.

Otherwise, if you're already aware of the limitations it relies on colorcorrection and a tonemap to fake it.

Well guys i dont want sunrise or whatever.
I just want the map gets dark and bright again. So thats only possible with color correction and tonemap?

Are there any tutorials according to that?

[TechieUK]

You mean something like this?

Best example I could find... You get to see the effect around 0:22.
I would do it through animated textures, especially as you could only animate world textures so enemies and props stay visible. Not much else I can suggest.

[opti2000]

Sorry not like that^^

Well i found something but somehow its not working i hope anyone can help me out.

Some people just parented a point_spotlight to a func_tracktrain and let it moved over the map. Like that it lokked like a sun moving from one side to another.

Does anyone know how exactly thats possible?

EDIT: And how is it possible to make the map entirely dark so that the point_spotlight light everthing up like a sun?

For example i just want it like this guy

[Major Banter]

That's with Lua, a coding language made use of in Garry's Mod.

Without significant code changes, this cannot be done in Hammer. Believe me, I've tried. If you're willing to delve into code, we can get more serious - otherwise the solutions will be hacky at best. I do have a few ideas involving dynamic lights but you will not get nice shadows, end of story.

[opti2000]

So the method with the point spotlight thats parented to a tracktrain will also not work?

[TechieUK]

If I recall correctly, point_spotlight doesn't make any light other than a tiny little spot at the end of it.
