Baked GI noise artifacts

Hello everyone,

I couldn't find any clear solution to my problem on other topic so I make my own.
I'm trying to add lighting to my scene, with Baked Global Illumination set on Baked Indirect mode.
When baking is done I get a lot of noisy artifacts, I spent hours tweaking settings trying to understand but I can't manage to get a descent lighting.
The only potential solution left I see is: enabling Generate Lightmap UVs on models.
Which I can't do since I use SNAPS prototype from Unity asset store, and for whatever reasons I don't have access to models properties.

I'm running out of ideas here, I would really need some help...
Also, I'm on Unity 2019.3.2f1 using URP.

Scene after baking:


Lighting settings:

 

I mean it looks like you figured out the issue on your own and I don't think there's a solution.

 

So you are saying there is no way to use Baked GI with unity's Snaps prototype assets ?
Would be a bummer that unity provide new assets not even compatible with their lighting system...

 

Finally got a solution to my problem!
Baked GI's working perfectly well now.

Since SNAPS and Pro Builder are related, I followed those steps:
1) Installed ProBuilder package.
2) Selected all my object in the scene.
2) Went to Edit -> Tools -> ProBuilder -> Object -> Pro Builderize.
3) It will add a ProBuilderMesh.cs script to all selected objects and within the inspector there is bunch of options such as a Generate Lightmap UVs button.

Would have been nice from unity to mention that part in their Snaps tutorial video when adding random colourful (useless) point lights.

Cheers,
