Strange Shadows/Contours in Detail View

When I use a rendered view in the display port, strange contour lines show up on the surfaces and meshes. I don’t get the same lines when looking at the regular top viewport. Turning the sun on kind of hides it but it is not what I want. Any ideas?

Shadows look like Contours.3dm (9.1 MB)

Hi Chad the camera Z in that detail is very large, so the shading steps are very deep, meaning that there are only a few in the depth occupied by the object. Activate that detail, unlock it, and set the camera Z to a smller number like 1000, then lock it again. Any better?

Perfect. Thank you so much.
