Thank you for the reply. I will read over that thread.

Yeah I don't edit any geometry after I export. But a lot of times the geo was coming in with faceted N gons. To fix this sometimes you can select the faulty polygon and bevel it in 1mm and it would flatten it, but a lot of times this wouldn't work and the facets would show up in the render. I heard there are new export options in v3 in the preferences for modo. Just wondering if that fixed this problem.

Thanks again.
