Yeti is Peregrine Labs new product focused on fur, feathers, leaves and generating lots of things based around familiar working concepts of a procedural graph directly within Autodesk’s Maya. The toolset has been developed as an end to end solution that easily integrates into most pipelines with ease and built with the goal of efficiently transporting and rendering the data generated while maintaining an artist friendly workflow. Yeti aims to be package agnostic and supports various rendering engines including Pixar’s Renderman and 3Delight with support for others coming soon.
Objects, grooms and guides ( nurbs curves ) can be imported into the graph from Maya as sources for the procedural network with all parameters controlled via SeExpr embedded into the application.
As parameters change and nodes are added to the graph the Maya viewport updates to help visualize the final effect with full control over viewport density for quicker/more accurate feedback.
Yeti is specifically designed to integrate smoothly into high-end visual effects pipelines, and offers a range of brush-based grooming tools, including the option to create ‘corrective grooms’ to finesse simulation results.
Unlike many other hair-simulation systems, the grooms are not dependent on surface topology or texture UVs, and may be exported as independent files – for application to multiple characters, for example.
A built-in caching system keeps file sizes low, only storing the information necessary to regenerate hairs at render time. The developer claims that cache sizes of 5-10MB per frame are typical.
