I am trying to import a simple ring with another piece of geo inside of it but I can see the edges on my outside ring. I thought that Unity would have the ability to hide or smooth the mesh edges. There has to be a better solution than just increasing the poly count of the ring to ungodly numbers.
You need to make sure the mesh has smoothed normals on those outside edges. In the modeling app, you can set the faces to be “smooth shaded” or “auto smooth” to keep the 90º edge crisp. But also in Unity, click on the model asset and look at the Inspector to see the import settings, where there are adjustments available on how to import or recalculate the normals for the model.

Thanks so much. I kept trying to fix it in Unity but I needed to fix it in Blender. Object Mode → Select object → right click → Shade Auto Smooth.
