CS:GO Need lighting help

[goss343]

Hello, I am new to the site and I created this account to ask a question that has been bugging me for awhile now and cant seem to fix. Its not really a problem but I need advice on how to light the room below. As you can see I have some lights above that are far away from the ground. Using normal lights and light_spot have proved unsuccessful. I intend the environment to be day outside and was wondering if anybody could shed some light (no pun intended) on this topic. The room length wise is around 2300 units. I have lots of lights in that order as you see below.

Is this what you wanted? I found it with the actual map file itself. Sorry, this is my first map and I'm new to this.

@goss343 It's always a good idea to look at how a real world location similar to your scene solve their lighting. In this case I'd put the lamps on the metal rafters to get them closer to the ground, and perhaps experiment with the ceiling height. Use light spots here. You can also add sky windows to get a more interesting environment, and more liggt spots on your walkway pillar.

[leplubodeslapin]

I wouldn't move the lights because they could really be there, you just have to configure the light_spot entities to cast light further away.

Try to configure your light_spots like this :

(For the Constant, Linear and Quadratic parameters). It should now be able, with the same intensity (Brightness 4th value) to cast light much further away than before.
You can find some examples in the beginning of that article i wrote a while ago :

You don't have to put hundreds of light_spots, even if you have that many models, you can put less frequently and make them more powerful.

You can share that part of your map in a vmf and I'll show you how i'd light this area.

Okay, thanks I'll try that and get back to you.

Being used to physically based lighting, is there any negative impact on using this approach with the Source engine? Or is it implemented in a way where it doesn't matter?

There's no negative impact on using this approach, it's actually a good way to do it.

The default falloff configuration is 100% Quadratic, which means the brightness dicrease by the square of the distance between the light source and its destination. This is the closest you can get for a "physically based" lighting. This is known in photography, if you take a picture of someone at a distance of 1 meter with artificial lights, and then you want to take the picture at 2 meters, you won't have to double your light intensity but multiply it by 4 (2^2).

In the real world, our eyes are incredibly good for adjusting to huge gap with light intensity and an enormous amount of light can lit a big room easily and you won't have any overexposed spot (pure white spot). And a moment later, you can go to another room that is barely lit and can still see shapes and stuff.

 

In games, HDR has been implemented to help with that but the range allowed by it is still extremely short (at least on source engine).

I think this video explains it pretty well :

(it's been a while since i saw it but i think it's the video)

 

So you have 2 solutions :

- You can lit your room with a classic quadratic falloff with huge intensity (2000 of brigthness! why not !) and adjust the exposure parameters of HDR to make it work, but you'll need extremely powerful lights everywhere to lit your map and will very easily have overexposed white spots everywhere.

- You can fake it with lights that cast light further away

I prefer the second one since i feel i have better control on it, but that's not mendatory.

[biXen]

Does anyone use it for CSGO though, or is it a half assed implementation? I know the linear workflow very well and I'm quite used to that. But your preferred solution is more along the lines of old Pixar, faking stuff to look good

It would be nice to have a base lighting with quadratic, and maybe use some fill light for ambience if need be, but so far it seems tricky. Guess it needs some more experimentation. I need to isolate things in smaller levels for testing I guess.

That's exactly what i'm doing. I'm trying to fill the space with ambience lights that cast light far away with low intensity. These light could be blue, green or red. And then i use white/orange/beige lights to do the actual lighting with artificial lights. This is how i've been able to do that for example :

(far from perfect examples ...)

 

Testing takes time because you have to compile the area with cordon tool and look at the map ingame, but you have to do it :-/

[biXen]

Well that's encouraging. Should be possible then to get a good result.

Hey everyone, thanks so much for the support and help. I finally got it working thanks to you guys!
