What's New in V4 

Ornatrix V4 is the next evolution of procedural hair, fur, and feather grooming in Cinema 4D. It brings the full 3ds Max V9 and Maya V5 feature set to Cinema 4D, together with several C4D-specific workflow improvements, so you can create, style, mesh, and export production-ready grooms - realistic hairstyles, stylized hair, fur, feathers, hair cards, and game-ready assets - in a fully non-destructive workflow.

The new features are summarized below, each linked to its documentation, followed by tutorial videos for the major additions.
