Particle and dynamic speckle brushes are new to Painter 2015 and 2016. They allow artists to create sweeps of "particles" (speckles, lights, dust, etc.) across the canvas with a single stroke. They are physics inspired, designed to mimic real-world particles as well as the behavior of brushes with individual hairs. In this course, John Derry, one of the original Corel Painter developers, introduces the new brushes and shows how to control the size, shape, density, and randomness of the effects.
