How Does It Work?
Use the Height and Width parameters to change the relative sizes of the scales without distorting the width of the edges of the scales.
Use the Sharpness and Overlap parameters to control how the scales look. Sharpness can be adjusted
from 0% (no point at all, or rectangular scales), to 100% (very sharp point, or diamond-shaped scales). Overlap sets the length of the vertical edge between adjacent scales. An Overlap of 0% means the edges
of adjacent scales touch only at the tip of the scale above them. An Overlap of 100% means there is a long straight edge between them.
Use the Edge_Width parameter to set the width of the scale edges. It can be adjusted from 0% (no edge) to 100% (no scale).
Use the Tilt parameter to set the tilt profile of the scales. It should only be linked to a generator. The Tilt
goes from the top(base) of the scale to the tip of the scale. In the color and percent versions, when the tilt generator is low, the values are darkened. In the bump version, when the Tilt generator is low, the
height of the scale is low. The default Tilt profile is linear.
Hints!
Use the Control class of components on the Sharpness and Overlap as well as the Scales to make the texture more varied and realistic.
Using the Tilt parameter is a little tricky. If you use a generator that does not start at 0% and end at
100%, the bump version will look strange. This has to do with how the scales are laid out. The tip of a scale has an edge, and the bottom of the edge has to be above the scale that is beneath it or the bump
will look odd. The Tilt parameter sets the height of the scale from the base to the tip. So if the Tilt parameter forces the tip of the scale to start below the base of the next scale, the result will look very
strange. Bias and Gain work well for Tilt.
