[CSGO] Light of entity 'light' looking blotchy ('solved')

[Sander]

This question was solved. Jump to the 'solution' right away

Hello everybody,

Been a while since I've been mapping for Source, but I am now making a new map for CSGO.

Everything runs great, except thing thing; the light coming from the 'light' entity is looking really really bad. Please see this screenshot:

Wrong light all over the place, but also good light.

The spotlights don't have this problem:

I have of course Google'd, but the only possible suggested solution I ran into was to place env_cubemap's; which I did, but without luck. Can anyone suggest how to resolve this issue?

Some more details:
- There is a (partial) outside which is using a Skybox
- HDR on/off doesn't matter, it is still there.

Is this a toggled light? CS:GO and toggleable lights do not mix at all, and this is the result of using one. It's not a well-known issue.

[ErikKiller]

What are your compile settings?

[Sander]

Thanks for your replies!

No, it is a very regular light entity, and I have not made it toggled.

What are your compile settings?

I use the Normal compile interface/settings:


In the meantime I have discovered that the spotlights and the regular light entity might be interfering. The spotlight seems to be causing really weird shadows. Does that maybe ring a bell with anyone? It's pretty confusing..

[WhiteDevil]

Compile with HDR on. I don't think csgo does even support non-HDR anymore, same as with L4D2.

Yep. CSGO doesn't do non-HDR. Therefore, what you're asking of the game is to only show 50% of lights and that's exactly what you're getting.
Enabling HDR should fix it.
I think this is also one of the reasons why fullbright 1 doesn't really work.

Thanks, it sounds hopeful, I'll try again tonight when I am home!

I know I stated in my opening post that HDR on/off doesn't make any difference, but after so much testing (and yes, I tried a lot before turning to you guys here ) I could of course be missing something.

Looking forward to try it out, will tell you the result as soon as I know.

Edit: this topic seems promising too: http://csgo.gamebanana.com/threads/184726 - found after searching on 'csgo hdr support'. There they said that if any light entity has a name, it will cause troubles too. Well, just a few more things to test.

[Sander]

And here is the solution:

Don't give light (or spotlights etc.) a name, or you will end up with these weird shadows. The exact technical reason is still unknown to me. Also, to compile with or without HDR does not matter.

Pity; controllable lights are not possible from CSGO (without looking bad).

[ErikKiller]

Giving a name to the light entity will make it dynamic, as far as I know, Source supports exactly one.
Don't give light entities names unless you REALLY need to.

Also tried it with one name, still messes up the whole thing in the area for that light. I ran some more tests (will show a screenshot later). Still, if anyone knows why Source goes completely bonkers when lights are 'named', I'd like to know (and probably others too)

[LordDz]

Why does the lights in that scene require names? Do you have buttons tied to them?
But it's mostly because source doesn't handle dynamic lights well, and as said - naming lights turn them into dynamic ones.

I used them mainly for grouping them internally in the editor - but I will move them to VisGroups now. I found using names for entities more convenient.

Eventually I wanted some lights to be switchable, but that is not possible anymore then probably.


Edit - and here is the screenshot with a little "research":

Thanks Erik, that clarifies it a bit more how naming lights affects the rendering.

[ErikKiller]

Usually, if you're unsure about an entity or you're just learning something new, just jump to https://developer.valvesoftware.com/wiki/ and search for the entity, read up on it, and then replicate/follow a tutorial. The tutorial will make a lot more sense and, hopefully, your brain will store the info about the entity somewhere for future reference/issues.
