Yes you're right Michael, I misread 3dm as 3ds, thanks for spotting that. I've used SteveMacc's suggested 6 degrees with n-gon export of and lwo with Lightwave 10 options and rendered in Modo 601, but there are still problems, I get the same holes in the reflectance either scaling to meters (which is the correct option to keep the materials all the right size), or not scaling to meters:



There seems to be two problems with Modo's rendering of n-gons from MOI

1) the reflection not being correct for non co-planar n-gons
2) the UV mapping of bump map having trouble with non co-planer n-gons

The only solution to get problem free renders is to using quad + tris for the export to Modo, adjusting the divide larger than and avoid smaller than settings to get a good division of the geometry. In the end the number of polys is around the same as for one of these more detailed n-gon exports, I was only trying to get n-gons working since I was told that they should work great with Modo, I'm happy to not use them and get on with it. Here are the correct renders of the knob done with quads+tris:
