The Hatching style emulates hatching animation that traditionally uses fine, tightly-packed lines to depict shading on objects. However, it can also be used to emulate stippling, by setting the hatching length to 0 (zero)—as seen in the second example in the video above.
To refine and customize the hatching style, a series of global hatching attributes are provided within the style configuration node.
Length of the hatching lines. If set to zero, produces a stippling effect.
Average width (thickness) of the hatching lines in pixels. A width of zero is invisible.
Controls the extent of the diffuse lighting gradient. A value of zero results in a binary shading style.
Smoothes the vector field used to orient the hatching lines. Higher values produce less abrupt changes in orientation.
The hatching style requires its own material: to set this material on an object, select an object and load one of the “_hatching” material presets (see material presets). Note that this material inherits most of the attributes of the uber material, which control the backdrop of the hatching lines. See uber for a description of those attributes.
Controls the overall density of the hatching lines.
If checked, enables the fractalization pass that ensures a constant line density regardless of camera position and zoom. This sometimes produces a slight “blending effect” when moving. Disable this attribute if your shot keeps the object at the same camera distance and zoom level.
