So, I have this problem with my mesh where one part of the mesh doesn't ever want to shade smoothly. No matter whatever I do the mesh's shader displays a harsh gradient akin to having soft edges on an non-beveled 90 degree corners. Doesn't matter if I try give it a hard edge, fill in the awkward hole that's hidden in the mesh or try and override it with a baked normal map - the problem persists in Maya.
Would appreciate it if someone could help me out with this matter, I've came through too many technical problems with this personal project to stop working on it. I've included the file for examination.
