You need the tablet to have a brush tilt function to use it. For example, on my two tablets, I use the same brush that requires a tilt function. No matter what angle you tilt the brush to, the thickness will only change with bamboooctl660. On the Intuos tablet, with the different tilt angles of your pressure-sensitive pen, the lines drawn will change differently (not just the thickness). Generally, ink calligraphy brushes (such as Linghua ink brushes) require this function. Simulates real ink painting and brush writing, which is very useful when designing brush fonts.
