3DPainter for Animation:Master (Windows, Intel Mac), 99$
Features - Brush System

The 3DPainter brush system offers a solid set of options to specify the brush for painting and cloning.

A brush can be generic (round with hardness setting) or defined by the alpha information of a bitmap.

If you have a drawing tablet, the size and/or the opacity of the brush stroke can be affected by the pen pressure.
