Hi Brian, if you want to dice that wall up into smaller polygons when you export from MoI, try using the "Divide larger than" setting for that.

You can enter a distance value in there, and any polygons that are longer than that distance will get subdivided.

So for your example there try entering the value 2 for "Divide larger than" and then push the Update mesh button - that should then give you more polygons. If you want more, start to bring that value down to 1 or 0.5 .

When you use the slider, that adjusts the angle parameter which will cause a denser mesh to be created on curved areas. When you have all flat planes in your object like you do in that case, the angle parameter will not really have an effect, the only thing that it will adjust in your model there is the density of that circular hole that is cut out.
