How to remove horizontal shadow strips


I have 2 horizontal gray (shadow) strips on my model.
One on the top and one on the bottom of my workspace.
I do not find how they appeared and how to remove them.

I am using Sketchup Pro 2023.


It is hard to tell with this infos …
Can you take a screenshot what you mean, and share your model?

sounds like the “safe zone” from either advanced camera tools or vray. or similar.

I do not have any of these plugins. Do you know how to remove this “safe zone”?

OK. Found. I installed VRay trial version and removed the safe zone. Thanks
