A new presets workflow lets you quickly share looks between meshes by applying premade grass or hairstyles to the meshes for an improved starting point. The XGen library now includes presets that were previously included with Maya Fur. You can also build a library of descriptions with custom thumbnails so you don't have to build them from scratch every time.
Sculpt guides more quickly and interactively with a new guide-sculpting brush. Width control on splines lets you create custom shapes for primitives, such as leaves, scales, and feathers. Multithreading speeds preview generation and interactivity, reducing the time spent waiting for primitives to generate on the surface. The new bounding box speeds previews in the viewport by reducing the number of polygons generated.
