Mike,
If you intend to reach natural-media look with your brushes, you need to, well, think like a brush:
1. In the brush that you posted you have scanned (or drew) several frames with elongated lines. Obviously, you wanted these brush strokes to be translated into brush strokes on the screen when put one after the other. But in fact what it creates, is a series of elongated lines, not more. A brush has hairs/fibers/bristles, and when dabbed once on a surface, it creates an area of
dots (the ends of the hairs). When pulled across a distance, and given that the approximation between the dots is close enough, these dots will create elongated lines. A clever bristle brush is not made of a single bitmap of a brush stroke (like photoshop has it), nor from a series of bitmaps of brsh strokes (like in your brush) but it is more like a particle system, in which each of the dots (bristle tips) move in progression within the defined area of the brush. In TVP we don't have a particle system, but we can still create a simulation of this system by using frames in the brush. I will post an example when I have more time.
2. Let's assume that your brush can still work nicely, even with its elongated lines. Still, in your brush, the lines were pitched vertically. In this case, your brush will seem 'natural' only in absolutely vertical strokes (top to bottom and vice versa). In any other way, and particularly in absolutely horizontal strokes, you will get the hard edges you referred to, and you will get blocky areas where pressure remains unchanging. If you turn your brush 90 degrees, and assign it's connection to
direction , you will get the brush always placed along the length of the elongated lines (see image).
