That looks like the kind of artifact that can happen with a rendering program having difficulty converting complex n-gons into triangles in order to do the render.

To avoid it, when you export out from MoI set the option for "Output: Quads & Triangles" instead of "Output: N-gons" here:

For this you need to assign the objects to different styles in MoI. When you export out to .obj, the styles list in MoI will become the materials list in the .obj file and style assignments will become material assignments.

So to do that select your objects that you want to have on a particular material, and assign them to a style by either clicking on the style's swatch in the scene browser or by using the Style menu in the properties panel:





Hope that helps, let me know if you still have any trouble.
