Thank you for your reply. I investigated your explanation but I’m not sure it’s correct. As a test, I flipped the plant upside down. I found that the side that was previously on the bottom, and white, was now on the top, and also displayed as white. What I found was that if I flipped the normals of my mesh, the white went away from the side originally on the bottom, and showed up on the original top side. It seems like the fact that this is a 2D object and has glossy enabled gives some kind of artifact? Does this make sense? Is this a known issue? Seems like the ray tracing gets confused for inward pointing normals.
