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
