Struggling with lightmap and normal maps... [URP - Android]

Unity Engine

Hi,

I’m looking for some help or explanations. I attach 2 screenshots, before and after baking my lightmaps.
As you can see, after baking my lightmaps, the ground looks very flat and the whole scene is over-lit.

Nothing really fancy in my settings (I guess), the lights are spots, set on Baked mode with soft shadows (default settings) and my materials are URP Lit, with only albedo and normal maps.
No directional, as the whole scene is included in a large sphere to avoid light leaks from outside the cave.

Unity 2020.3.6f1 LTS, URP, Android (the app is planned for Oculus Quest 2).

I tried a ton of modes, quality settings, etc. but I’m really stuck at simply baking theses lights and keeping the influence of normal maps…

Thanks !

This is a known limitation of our current directional lightmap implementation. If want to have the normals definition like the one you see prior to baking, you’d have to use mixed lights.

Thanks for your answer. :slight_smile:
That’s a really huge limitation though…
I ended up buying Bakery. I had to use the maximum quality settings and it’s not really optimized (I have a short deadline), but I managed to have a quite good result and it’s still responsive in a Quest 2.

Would you mind posting a screenshot of how your scene looks like now? It would be interesting to see.
