New in Version 4 

• Box and unbox
  • Boxing of whole or partial stack
  • Unboxing a groom operator to extract its constituent operators
  • Groom operator, containing multiple internal operators with ability to expose custom parameters
• Graft grooms (easy point and click creation of complete grooms on any character model)
  • Built-in eyebrow and hair graft grooms
  • Ability to create new grooms directly within Ornatrix
• Performance improvements
  • Switched to Embree 3, significantly improving performance in many places
  • Improved hair display performance
  • Using SIMD optimizations to further improve performance
• Surface Comb operator
  • Allow per-sink rotation adjustments
  • Added "flow" per-sink parameter
  • Channel export
  • Added an option to export sink groups to channel data
  • Exposed sink length setting to the MEL command
  • Added an option to set sink data values based on an absolute length
  • Dim strand channel controls in Surface Comb when not used
• Hair from Guides
  • Added "Hidden Guide Behavior" option for Hair from Guides (don't generate hair for hidden guides)
  • Parting Tool avoids object selection when in Edit mode if there are no parting planes
  • Multiple distributions maps to allow procedural density map blending
  • Guides from Hair distribution respects distribution map and channel
• Clumping
  • Added option to set strand groups based on clump ownership
  • "Ground Displaced Roots" option
  • Added an option to exclude already clumped strands from the selection
  • Added Multiplier map support to the Clump Size parameter
• Normalize operator
  • "By group" option separating its application by strand groups
  • Added a ramp curve
• Edit Guides operator
  • Allow to move only the roots of strands
  • Allow the Create brush to add strands per-vertex and per-polygon face
  • Preserve strand selection from brush to Control Point/Strand mode
  • Added mirroring support to the Draw tool
  • Update current Attribute Editor channel value based on selection
  • Comb by group options
  • Collision detection during combing options
  • Specify how selection changes when guides are planted
  • Planted guides are interpolated between all selected existing strands (previously only the nearest strand was used)
• Curl operator
  • Magnitude and Phase randomness for Curl
  • Add range values for Noise Scale parameter
• Filter operator
  • Added Channel and Map parameters to control random fraction to Filter operator
• Ground Strands operator
  • Added mesh evaluation at specified time when grounding
• Arnold render
  • Completed work on Arnold procedural
  • Deploy Arnold extension for both MtoA 4 and 5 in Maya 2019+
• Baked hair
  • Operator baking now supports baking strand widths
  • Implemented full-stack import with BakedHairNode
• Animation cache operator
  • Ability to key-frame animation
• Automatic change tracking of select operators
• Using Texture Coordinate method for calculating vertex tangents (improved hair smoothness/consistency across surface)
• Using UV-based vertex tangents by default
• Switch vertex tangents to use Texture Coordinate generation method by default
• Using geodesic distance by default to calculate strand group blending effect
• Added .oxg.zip groom analogs of existing .oxgroom files
• Maya 2023 support
• Updated icons
• Marking/context menus
• Add "Use Procedural Meshes" option to USD groom export
• Updated VrayOxHairMaya to work with VRay 5 SDK
