Baked light is black

[limpid mantle]

On mixed it works (still not properly), but when i set to baked it is just black

Quick answers:
Have i set object to static? Yes, i tried both static and not static
Have i checked the contribute global illumination checkmark? Yes, tried both checked and unchecked

Define "works but not properly"
Are you trying to use Realtime GI or just Baked GI

[limpid mantle]

Light works, but the light is visible even through walls
| - Wall

Baked, but tried disabling/enabling both, nothing helped

[limpid mantle]

Walls are perfectly fine, geometry is good and they are double sided

[cloud garden]

Why this ascii art instead of a screenshot?

[cloud garden]

If you're not sure which type of GI you need, do you know what type of lighting in general you're after?

Baked GI and realtime GI are totally different systems, and they're both different from realtime lighting

[limpid mantle]

Checked, realtime GI

[cloud garden]

Elaborate?

You mentioned using mixed and baked type lights, which contradicts trying to use realtime GI

[limpid mantle]

dont it work with mixed?

I guess it was placebo effect when j was turning it on and off

i mean, if baked mode works only with baked GI, i have to use that

realtime uses too much resources, mixed too

baked is the only way it is optimized without big quality loss

it worked before, but after the project crashed it is broken now

[cloud garden]

I'm not getting much information about what you're trying to achieve

And it seems you don't exactly know yet what the different lighting methods do or how they should be used?

[limpid mantle]

Baked lights, but it is not showing up correctly

I will send screenshot

Give me one minute

it looks like this with baked light

[cloud garden]

Then you don't want to bake Realtime GI at the same time

[limpid mantle]

I tried disabling it, but it does nothing

[cloud garden]

Expected, it's just unnecessary to generate another set of lightmaps that you won't need

[limpid mantle]

Yeah, thanks for that

mixed light

The steps to baked lighting in short are to
-have Baked type lights with sufficient range and intensity
-set environment geometry as Contribute GI static and to receive GI from lightmaps (unless you want to use probes)
-enable lightmap UV generation from mesh import settings for all meshes that should be lightmapped, if using custom meshes

Keep Direct Contribution, Indirect Contribution as well as Albedo Boost and Indirect Contribution all at 1 unless you have artistic reasons to change those once lightmapping works okay

[limpid mantle]

i tried setting the static only to contribute GI, yet no changes

[cloud garden]

If you're using ProBuilder, lightmap UV generation will have to be enabled from ProBuilder

After all that and Generating, the area in inspector below the lighting settings should give you a recap of what it has baked

[limpid mantle]

I dont use ProBuilder

[limpid mantle]

Direct contribution was set to 0, but even with it changed to 1 everything still black

[cloud garden]

So, this tells us it's baking light in some form on some of the objects

https://docs.unity3d.com/Manual/GIVis.html
Which means these draw modes should produce some kind of information

It would allow you to see the baked lightmaps directly without any textures in the way, as well as to ensure there's no UV overlap to prevent lightmaps from being applied

1: Contributors and Recivers
2: Baked Lightmaps
3: UV Overlap
4: Light Overlap
5: Directionality

[cloud garden]

Which render pipeline was it?

[limpid mantle]

hdrp

[limpid mantle]

something wrong with the light overlap right?

[cloud garden]

All of these look okay

Except the discrepancy that it seems there's a lot of light captured on the lightmaps but we see none of it

Since you're on HDRP you should check for exposure

It's possible that your emissive ceiling lights are so bright, that with an exposure that doesn't overblow them all actual light is close to black

[limpid mantle]

from the volume?

[cloud garden]

So temporarily disable the emissive ceiling lights and turn up the exposure override

Yes
Even just disabling the light fixtures may cause lighting to become visible, if you're using automatic exposure

[limpid mantle]

setting it to -5 gives this

[cloud garden]

Can you disable the ceiling fixtures?

[limpid mantle]

like the emissive material?

[cloud garden]

Either disable the emission from the material or the objects themselves

Which were highlighted orange in your contributors / receivers view

Once they're gone, you should be able to test more exposure levels without them blowing out the brightness

Although since they didn't do that on -5 exposure I guess you may be using exposure-independent emission for them

[cloud garden]

This doesn't tell me much yet
We see some light but it's dithered in a way lightmaps should not be
So it could be something else, like SSR

It also resembles APV lighting, but the contributors / receivers view appeared to confirm they were lit by lightmaps, not probes

[limpid mantle]

could it be because of screen space global illumination?

[cloud garden]

Very well could

[cloud garden]

What's the context of this?

[limpid mantle]

after setting non-emissive material

[cloud garden]

After that, you should try all exposure values to see if the light comes into view

When I say "I guess you may be using exposure-independent emission" that implies I'm interested to know if you were, or if it rings any bells at all

[limpid mantle]

So, i disabled the SSGI and it works, but now problem is that the light is coming

[limpid mantle]

Theres no gaps in the walls

[limpid mantle]

Thank you for the answers!!!

[cloud garden]

one problem down

[cloud garden]

Hm, what kind of lights are you using exactly?

[limpid mantle]

Area lights

[cloud garden]

With what kind of size and other properties?

[limpid mantle]

enabling baked shadows fixed it

thank you!!!!!!!!!!!
