The Stylized Hatching mainly happens in a DisplayFilter node, with optional information on a per-object basis from PxrStylizedControl.
Can be used on its own for simple cool styles or combined together (daisy-chained) with other Hatching nodes, or Toon & Lines nodes. When daisy-chaining Hatching with the other Stylized nodes, an ideal order is Hatching, then Lines on top. You can combine multiple Hatching and use the Mask/Input Mask feature on the node to mask them together based on different input signals (light sources, camera range, ...).
