Yeti is Peregrine Labs new product focused on producing procedurally generated solutions such as fur, feathers and leaves within Autodesk 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 1.0 new features include:


  • Changing UVs and Topology handled gracefully
  • Non destructive Procedural workflow
  • Embedded expression language
  • Fully integrated into Maya
  • Support for corrective grooming post-dynamics
  • Separate display and render attributes
  • Visual graph editor for node networks
  • Unlimited number of surfaces, grooms and guide curves
  • Integrated caching
  • Groom based referencing system to easily publish and inherit groom styles
  • Publishable groom files that store a whole groom in a single file for easy versioning and asset management


  • Non topology specific
  • Strands can be placed anywhere on a surface at any density
  • Unlimited number of user attributes can be created and painting
  • Export/import any attribute to/from a 2d texture
  • Comb and sculpting modes
  • Mirroring
  • Full control over brush shape and response
  • Use Maya component mode to pick and shape strands


  • Fully procedural
  • Expression based node parameters
  • Any number of data streams that can be merged
  • Multi-leveled clumping
  • Instance geometry to points and fur
  • Comb and deform fur based on grooms and guide curves
  • Create and modify attributes
  • Group points and fur based on bounding geometry

Rendering and Dynamics

  • Rendertime evaluation via DSO
  • Rendering attributes ( density etc. ) can be changed without re-caching
  • Command line PTC generator for point based Occlusion and GI
  • SL Shader source provided
  • Ability to pass custom surface attributes to shader for render time effects
  • Groom based high quality dynamics solver
  • Support for Maya fields
  • Any number of input collision meshes
