What you must also be aware of is that reducing the Max Smoothing Angle may
affect other areas of your bevel that you might not want sharpened. If a letter
does a tight turn, for instance, and the angle between two bevel surfaces are
greater than 40, you'll get an edge that you didn't ask for. OTOH, Max
Smoothing is great for displacement mapped landscapes, to give it that
unpredictable jaggy look. I usually use something like 65-70 degrees on my land
surfaces..
