Shadows Issue, Surfaces go black

Hey guys,

I have an issue with the my shadows on Rhino 6. I have never seen this kind of problem before. I don’t remember changing much of the setting and not sure how it even occur. So basically when I zoom in to a surface it turn black. I have attached three photos. 1. Further away, 2. A bit zoomed in, 3.Very much zoomed in. There you can see the issue I am talking about. Please help me out!

Thank you in advance,

Aleksandar Donov

Hi Aleksandar - can you please run the SystemInfo command and post the results here? Are your objects very far from the origin?

This is the info from the command. I have set the origin at the bottom of my model, I don’t think that the problem is the origin. Hopefully this information helps.
