Orbit tool is causing my model to look different



I’m not sure if I’ll explain this the right way but my model is a building with a wood floor. its a really simple layout. so far there’s no ceiling and the floor is just a wooden rectangle pattern. the problem is when i orbit the layout around parts of the floor look grey. Can anyone help me out here?


Hello. Upload your file here, so we can have a look, please.


I figured out the issue. but thank you so much.


And the solution was?


deleting and reinstalling the floor. i’m not sure how it fixed the problem but it did.


Sounds like z-fighting from 2 faces in the same plane.
