Recently, Epic Games unveiled a system for rendering realistic-looking hair and fur in real time. In Grooming for real-time realism, we describe how the system implements advances in hair and fur rendering to make this process work faster than ever. The white paper explores two use cases: human hair as seen in our MetaHuman Creator announcement video, and fur and feathers from the Meerkat video created by Weta Digital. For both cases, we take an in-depth look at the grooming process including various workflows, best practices, styling and mapping techniques, and much more. Additionally, both the Meerkat demo scene and MetaHumans examples are available as free downloads, so you can see the techniques in action right away.
