The appearance and movement of hair are so interdependent processes that they cannot be done separately in most cases. How to make hair look amazing and not ruin everything later? :))) How not to break the visual appearance of hair by simulation? What should be done at the grooming stage to effectively use simulation later for artistic image improvement? Different hairstyles have different problems and require different approaches to solve the problems. I will show my workflow of creating different types of hair and talk about how Houdini helps me to solve the above problems due to its procedural nature.
