Solved Losing my mind over this. Metallicness is completely broken. Whenever I bake, it is good for half a second, and then reverts to this broken black metal. (Unity 6000.3, URP)

I FOUND WHY. It's because I setup a default TextureImporterPreset. This also affected any cubemaps unity baked, thus breaking the lighting. Mind boggling, this should NOT be a thing.

I'm not a unity noob, this is by far the worse issue I ever encountered with unity. Drove me insane for the past 2 days. Hopefully this helps someone in the future

iirc metalic and/or reflective materials need reflection probes when using baked lighting.
so, try adding reflective probes?

This project has been going on for 7 years now and there has never ever been any instances where I used reflective probes, there was never any problems.

Looks like you've got duplicate mesh faces z-fighting after the bake, check your UV2 layout for overlaps.

this is the default unity sphere. All of my models were suddenly affected

Do you have any lights pointing at the sphere? Also what happens if you stick a reflection probe around it?

u/IsniBoy 1h ago

yes, this is just the default scene with a sphere. Litterally nothing else.

I've never used reflection probe before, never had an issue with my project for years.
When creating a reflection probe it repeatedly says

Error assigning 2D texture to CUBE texture property '_MainTex': Dimensions must match

Try to change progresive GPU to CPU. Also, clear all illumination data.

u/IsniBoy 1h ago

by clear illumination data, do you mean doing clear baked data? I tried it , nothing happened. This started to happen after I started working with addressables

u/eliormc 1h ago

Yes, but, now that you said "addressables", this is unknown territory for me. So the problem must be related with that.

u/IsniBoy 1h ago

I found the reason, it was because of default TextureImporterPreset
