Why my images are rendered like it they have fingerprints?

Hi all!

Don´t know when it started but I was on the creative path experimenting with baked lights.
From that point, everything I do comes out with this weird fingerprint look and artifacts.

Could anybody tell me how to fix it?
It would also be helpful to know where to control the resolution and the camera I am rendering.
Thank you very much!

 

looks like a moiré pattern to me and is as such an aliasing artifact. Make sure to use mipmapping on your textures and an aniso level of at least 4

 

Thank you so much but, what is mipmapping and where do I find this aniso level? Excuse my lack of knowledge. I am just brand new at Unity.

 

Looks like shadow acne, try changing the shadowmap bias for each lights.

 

This is exactly what happens! Thanks! Now, I had the Bias on "Use Pipeline Settings" but can´t find those, could you tell me where it is?
