Let's keep going here

#

Ok I took a look at your logs

#

An initial thing that stands out: is there any particular reason you are using Enlighten?

hollow delta Dec 18, 2022, 12:35 AM

#

i don't know what that is

foggy hull Dec 18, 2022, 12:35 AM

#

I know it's there, but it' worse than the other two options

#

Ok wait

#

Do you have "Realtime GI" enabled?

hollow delta Dec 18, 2022, 12:36 AM

#

don't know

foggy hull Dec 18, 2022, 12:36 AM

#

Can you send me a screencap of the entire lighting window?

hollow delta Dec 18, 2022, 12:36 AM

#

i don't usually mess with a lot of settings, i do programming mostly

#

foggy hull Dec 18, 2022, 12:38 AM

#

It may be slowing down your bake. I also recommend updating to most recent 2020.3 if you have to stay on the 2020 versions or going all the way up to 2021.3

hollow delta Dec 18, 2022, 12:39 AM

#

I just prefer to stay on the same version to not have any updates mess up anything i have already
Has happened before and it took hours to get back to normal

foggy hull Dec 18, 2022, 12:39 AM

#

Oh interesting. Can you click where it says "Progressive GPU (Preview)" and send me the options you see?

foggy hull Dec 18, 2022, 12:39 AM

#

hollow delta I just prefer to stay on the same version to not have any updates mess up anythi...

Makes sense

hollow delta Dec 18, 2022, 12:39 AM

#

foggy hull Dec 18, 2022, 12:40 AM

#

So even though you have GPU selected you're somehow kicking off a lot of Enlighten jobs which seem to loop around themselves

#

Did you only click generate lighting once or click auto generate?

#

Or smth else?

hollow delta Dec 18, 2022, 12:41 AM

#

so they are going into a recursive state basically
and no, i did not press generate at any time
i have it on auto generate

foggy hull Dec 18, 2022, 12:42 AM

#

Hmm ok that explains it

#

I think there's something messing with auto generate here where it enters a broken state

#

Not sure how you're getting enlighten jobs with no realtime gi

hollow delta Dec 18, 2022, 12:44 AM

#

🤷‍♂️

foggy hull Dec 18, 2022, 12:44 AM

#

Can you dupe your project and see if you can upgrade?

#

Make a backup basically

hollow delta Dec 18, 2022, 12:44 AM

#

sure

foggy hull Dec 18, 2022, 12:44 AM

#

And don't use auto generate it's kind of bad (sorry)

#

As in I hate it and we're sort of getting rid of it

hollow delta Dec 18, 2022, 12:45 AM

#

ok

foggy hull Dec 18, 2022, 12:46 AM

#

I think going to latest 2020 is safe

#

No new features, just bugfixes go into LTS minor versions

hollow delta Dec 18, 2022, 12:46 AM

#

i dont know if it's a unity thing or windows thing
but this copy-paste the folder seems super slow (it is on an m.2 ssd)

foggy hull Dec 18, 2022, 12:47 AM

#

If it takes too long delete the library, logs and temp folders and try again

#

(They are generated by the editor it's non-destructive)

#

But if that's too scary I understand

hollow delta Dec 18, 2022, 12:49 AM

#

i didnt even get the update message this time going into the duplicated project
just restart unity?

foggy hull Dec 18, 2022, 12:50 AM

#

Can you check the title bar for the version?

hollow delta Dec 18, 2022, 12:50 AM

#

foggy hull Dec 18, 2022, 12:50 AM

#

Ok download latest 2020.3 and open in that

hollow delta Dec 18, 2022, 12:51 AM

#

ok, downloading through the hub

foggy hull Dec 18, 2022, 12:59 AM

#

Did someone else by any chance generate lighting for this scene before you and then pass on the project?

hollow delta Dec 18, 2022, 1:00 AM

#

no, im alone on this project
created it and only one worked on it

foggy hull Dec 18, 2022, 1:00 AM

#

Did you maybe work on it on a different computer?

hollow delta Dec 18, 2022, 1:01 AM

#

i have opened the project on an older laptop
but i dont think i transferred the project back to my pc
i transferred through usb

foggy hull Dec 18, 2022, 1:02 AM

#

Ok so your main PC has been handling the project

hollow delta Dec 18, 2022, 1:02 AM

#

yes

foggy hull Dec 18, 2022, 1:03 AM

#

Ok im asking this because if you baked with the Enlighten backend on separate computers there's a chance their gi caches went out of sync and are causing this hiccup

#

But seems not to be the case

#

Just a hunch. Did the editor install?

hollow delta Dec 18, 2022, 1:04 AM

#

i dont think thats the case
i opened this project on the older laptop a while back and have done baking after that on my main pc

hollow delta Dec 18, 2022, 1:04 AM

#

foggy hull Just a hunch. Did the editor install?

yes, opening the project right now in the newer version

foggy hull Dec 18, 2022, 1:05 AM

#

Alright nice hopefully no borked shaders 🙂

#

I did find this in your log btw
[PathTracer] Failed to render lightmap with hash: 79edbc228a0ec64e906396d147b0d478 -> scheduledDirect: 0rpt, scheduledGI: 0rpt, scheduledEnv: 0rpt
[PathTracer] Failed to render lightmap with hash: eb0c58f6a114f16d018f388b449236d3 -> scheduledDirect: 0rpt, scheduledGI: 0rpt, scheduledEnv: 0rpt

#

No clue what that error is, looks like the lightmapper scheduled 0 rays per texel 🤔 and then broke

#

Which either means that you have a really terrible mesh or we have/had a bug

hollow delta Dec 18, 2022, 1:08 AM

#

when is that error from?

foggy hull Dec 18, 2022, 1:08 AM

#

The first file you sent

hollow delta Dec 18, 2022, 1:09 AM

#

i did get the mesh from a guy i worked with, and he did give me a lot of broken meshes at first until i fixed them

foggy hull Dec 18, 2022, 1:09 AM

#

The second file looks like it's baking with enlighten

hollow delta Dec 18, 2022, 1:10 AM

#

anyway, even with crazy high lighting settings and indirect multipliers
it is going really quick now

#

also had no errors with the updating to latest 2020 version

foggy hull Dec 18, 2022, 1:10 AM

#

500 samples is pretty standard

#

Check the 2023.1 manual for sample counts I just rewrote it :))

hollow delta Dec 18, 2022, 1:11 AM

#

increased to 5000, and still not taking too long

foggy hull Dec 18, 2022, 1:11 AM

#

hollow delta anyway, even with crazy high lighting settings and indirect multipliers it is go...

Yeah as it should with gpu

foggy hull Dec 18, 2022, 1:12 AM

#

hollow delta increased to 5000, and still not taking too long

Are you getting decent results?

hollow delta Dec 18, 2022, 1:12 AM

#

yes, absolutely

#

roughly 6 minutes left on baking

foggy hull Dec 18, 2022, 1:12 AM

#

Fantastic then problem solved 😎

hollow delta Dec 18, 2022, 1:12 AM

#

thanks a lot 👍

foggy hull Dec 18, 2022, 1:13 AM

#

I recommend in the future using 2021.3 and don't use auto generate it's bad 😦

#

No worries, have fun with the project!

terse condor Dec 18, 2022, 9:58 AM

foggy hull I recommend in the future using 2021.3 and don't use auto generate it's bad 😦

That has seemed to be the case
Does it do the generation itself in some fundamentally different way?

foggy hull Dec 18, 2022, 11:08 AM

#

terse condor That has seemed to be the case Does it do the generation itself in some fundamen...

No, it uses the same backend but it saves the lighting data asset in the gi cache instead of in the project

#

Most of the crashes and more serious issues we have gotten on the progressive lightmapper have been timing based because you can restart the bake over and over

#

So in 2023.1 we only use the progressive backend in auto mode and have rewritten baking completely for on-demand

#

So it's now a separate thread and doesn't use any global state / state machine logic to restart jobs and sometimes crash.

#

Generally auto mode is bad news because it's unstable and we've been talking about deleting it for the longest time 💀
