Wireframe Lines Coming Through

It looks the surface is subdivided into triangles, and two of them are almost singular (ie they have a nearly zero height). Then calculation of the normal is then likely messed up (computing the normal of a nearly singular triangle is very prone to precision issues)

Subdividing will maybe solve the problem, but Indigo will not subdivide unless there is displacement mapping.

I would try doing some manual subdivisions in sketchup : for instance, create a rectangle surrounding the hole on the face.

Sorry for replying so late...I must have missed your post on page 2. Adding a rectangle around the problem areas (curves) only intensifies the problem. This should be reproducible by anyone.

Make a surface and put a circle in it. Then apply the brushed aluminum material.
