I am extremely new to blender, and have a very basic idea how to use the tools to create models for games I would like to make. I am in the middle of making a simple pizza slice, and all went well during the creation, but when I exported to a .FBX file, the resulting model had weird glitch-looking lines where the "mushrooms" on the pizza slice are. I hope that someone out there more knowledgeable than me can explain the issue to me so I know for the future, as I have only watched two tutorials to learn the complete basics. Thank you!
P.S. I only screenshotted one of the mushrooms on the slice, but both are having the same issue that I tried to describe.
