Hi niko - no problem! Yeah basically something with subtle dimples in it like that can look worse than it really is when the display mesh ends up with only one polygon vertex created inside that dimple, especially if the polygons are kind of long.

Stuff that's curved pretty tightly in one direction like this but not so curved in the other direction will tend to make long polygons in the less curved direction, but "Divide larger than" at export time can help with that.

Sometimes you may actually want to do a test export when you see something like that so you can see if it's really not such a bad thing once you get enough polygons created for displaying it.
