Square field on sphere when getting light from an emission
For some reason there is some kind of square field on my sphere when i use an emission on a plane. The plane and sphere are both static.
I'm using Unity 2018.1. Check the screenshot-62.png file for more information.

I'm experiencing the same thing. Happens on capsules too. The "edges" of the square field rotate along with the objects.
Edit: I found the problem when I baked in the lighting from a directional light. The spheres have UV map overlap issues. The "square fields" you're seeing are actually each of the uv maps. The Unity sphere is represented by a cube that's been distorted. Those are the seams. To fix the problem, it is better to use a sphere brought in from outside unity. But you can alleviate it by increasing the resolution of the lightmap both on the sphere and in the general lighting settings.
