After inspecting the model in 3dsmax, I found a few surface incontinuities in the topology which could result in some issues when importing into certain software packages. There are some unwelded vertices and overlapping edges in this part of the model...

Easily fixed, but the complexity of the boolean stitched polygons has created a lot of triangles and ngons that would need to be fixed as well. The model imported just fine in 3dsmax, but there are some shading glitches because of the polygon problems that do also show up in the render.
