Hi Leonard,

> The pic below shows what trangulate does for the mesh.

You may want to export as Triangles directly out from MoI for a case like this. MoI's triangulator will put center points in for n-gons that can be triangulated in a radial manner, which can help to reduce some of the more skinny triangles.

It's not so much for "up close" shots, but more that smaller polygons will reduce shading artifacts.

Remember - polygons are not actually smooth at all, they are only little flat pieces and the shading is done by a kind of trick.

If your polygons have too much variation between each adjacent one, that can tend to cause shading artifacts where the smooth shading trick does not work as well to make those flat pieces appear as if they were a smooth surface.
