Maya/arnold, Normal issues on the edge of the mesh.

Hey Im encountering a problem with the normals on the edge of my mesh and I cant seem to figure out how to fix it. It renders fine using Iray in substance painter and blender cycles, but not with Arnold in Maya. Anyone know what could be causeing the black areas and how I can fix it?

Apologies if this is posted in the wrong section, I'm brand new to the forum.

Here you can see the areas where its black on the edges of the mesh.

Here is two images of the mesh itself for the area marked one.

Here is how it appears in Iray, no normal issues from what I can see.
