Be it relative or constant, the level of detail is all about the object. When you are in relative detail, it will be relative to how zoomed in or zoomed out you are from your object. If you are very zoomed in, you will have finer detail when you lay a stroke with your brush than if you are zoomed out, because it’s relative to your distance according to screen pixel size. But then this creates the problem that you have to be zooming in and out depending of the level of detail you want in your object. So that’s when constant details comes in, now it doesn’t take into account how zoomed in or out you are to the object, when you lay a stroke the detail will remain the same no matter your distant to your object in the viewport. So remember, it’s all about the resolution on the count of polygons that will be created each time you lay a stroke on your object, not your brush size in the screen.
