LOD0 too dark compared to LOD1, 2 & 3

Hey everyone!

So I'm having a strange issue in 2017.3.1f with prefabs using LOD groups, where LOD0 always looks a bit more dark than all the other LODs. The difference is subtle, but too noticeable for me to ignore. Each model is using the same materials and the problem happens in lit as well as unlit environments. So I'm assuming this is not a lighting issue, but I'm not 100% sure. The problem happens to models from the same fbx, all of which have the same import settings. Has anybody encountered this problem?

Do you have baked lighting?

 

No, I'm using realtime lighting

 

Ok. Baked lighting could have explained it as LOD1 + needs lightprobes to sample the light. Only LOD0 is used for enlighten.

Thanks for the info! I think I noticed it was just a lack of building lighting. Problem looks solved now. For future reference, I ended up not needing light probes.
