I am sure someone out there has experienced this issue, but without knowing exactly how to describe what is happening I wasn't entirely sure how to search it. Basically, everything looks great using Eevee, but when I switch to Cycles...things get strange. I am including a screengrab.
This never has happened before using my Mac, but I recently got a PC and this is the first model I have done on it so I am not sure if there is a setting I have gotten wrong. As this is my first model I have not altered any settings personally.
