Lights don´t interact correctly in a plane with textures.

I have some problems with how the light interact with the floor plane. It seem a part of it does not receive any ilumination. I have 3 area lights in the roof. When i move the camera, it look like if the lights are not bouncing in the floor correctly. I´d appreciate if someone could help me with this one, I´ve been dealing with this for quite a time now.

What sampling settings are you using? What happens when you assign a default Standard Surface shader to the floor? Is there light linking in the scene? Can you upload the scene?

Hi! I figure it out. The normal map had the R and G channels in flip and they weren´t supposed to be. That fixed the problem completely.

Of course, that makes sense! :)
