Hi Ty, it probably would be a good idea to send KeyShot a demonstration model where it's getting the rounded corners messed up so they might be able to figure out what's going wrong with it and fix it up in some future release.

Maybe it's sensitive to long skinny triangles (kind of looks like it from your screenshot) - if that's the case then the steps you are doing, especially with using the "Divide larger than" setting should help with that, I would think.

But it sounds like you're running into some bug or limitation in the KeyShot function so it would be good for them to know about that so they could try to improve that area of KeyShot.

Your steps sound good to me - the main thing for KeyShot will be to use either the "Output: Quads & Triangles" or "Output: Triangles only" settings since KeyShot does not like to handle complex n-gons (polygons with more than 3 or 4 sides). Other than that the other settings are just up to your own personal preference of what looks good. The ideal "Divide larger than" setting can vary depending on the size of your particular model you are exporting - if you have a model where 4 units is very small in relation to that particular model size then you want to put in a bigger value there. MoI will divide up polygons until they are smaller than the distance that you put in for that control. That additional dividing can help to make more evenly sized polygons and helps to avoid long and skinny triangles so if that's what bothers KeyShot's edge rounding that may help it.
