Hi @GamingMonkey1028, this is definitely an odd problem. My first instinct is to say Nanite is causing this, so I’m surprised to hear this got you nowhere.
My next instinct is to say some normals are getting inverted. It’s hard to tell, but the missing areas look like they’re square-shaped, so this would make sense.
Either way, I would start by trying to narrow down where this issue is coming from. Can you send some SSs of your material editor, to make sure nothing in the material is causing the issue? Can you send some photos of the meshes- both inside the meshes and outside?
