Software crash when trying to use baking global illumination on a mdl based level with around 100'000 polycount

[WuotanStudios]

I tried to use a probe in my Dungeon Level ( example video made in godot : X.XOM RIAD example video in Godot

)

I imported the Level as glb model and made it to a mdl -> dragged and dropped the mdl into the Level.
I placed the probe and hit "baking global illumination"  -> this ends in a software crash without any error, after around a half minute of loading.
The Textures used on this model are in 2k resolution, if that info matters.

Can you upload the model and map files please, so I can try it out?

[WuotanStudios]

The File Size as Project / Map is 160MB.
Updload won't work here.

But i can upload the mdl file with 68MB.
Simply start a new project, drag and drop the dungeon_design_1.mdl 

Place the Probe there and try to bake.... in my case Leadwerks shuts down after a few secs every time i try it.

I extract the model to Models/RIAD/dungeon_design_1.mdl, created a probe, and built global illumination. No error occured.

It would be helpful if I could see your scene file and all files it uses. Otherwise there isn't anything I can test.

I increased the single-file upload size limit to 200 MB.

same setup here:
i started an empty new c++ project. no other files or objects, only that model and the probe -> baking = crash

i've recorded it this time, see attached file
As soon as i try to bake, crash , ultra editor closes (the moment the video turns black)

my machine specs: 
windows 11,
AMD Ryzen 5 7600X,
64GB RAM,
NVIDIA RTX 3060

Made another test:

i simply made a new project and used your original horror fps template -> hit bake -> crash

So it has nothing to do with my 3d model, it is a general issue on my machine.

Maybe it's related to hardware? AMD Graphics card? Driver version?

[WuotanStudios]

i have an NVIDIA card.
Drivers are up to date.
I will test it later on my laptop, which has also NVIDIA , but the RTX4070.
Lets see if it works there.

[Josh]

Sorry you are having a problem. That definitely should not happen.

One question, in Tools > Options > Video, what is your Shadow quality setting set to?

[WuotanStudios]

On my laptop it works, no crash.

@Joshh i will look into it as soon as i am back on my desktop pc.

[WuotanStudios]

So i am back on my desktop PC with the NVIDIA 3060

Shadow quality = 100%

Meanwhile i've reinstalled the nvidia driver, and ultraengine too
but nothing helped -> still same issue, even i make a minimalistic scene with just a box, a light and the probe.

i have no clue why it happens on this computer.

[Josh]

Maybe I can pick up a GEForce 3060 soon! What is the maker of the card? ASUS, Gigabyte, MSI, etc?

[WuotanStudios]

Gigabyte in my case, it is the Gigabyte RTX360 12GB variation

[WuotanStudios]

Before you buy a RTX3060, my son also has one in his computer.
I will test it on his computer too. 
Lets see if it is really something the RTX3060 causes.
My gut tells me it is something else

[WuotanStudios]

sorry, can't test it on my sons computer -> i can't share software through steam.
I won't buy another license for testing, sorry.
