This video goes over some of the workflow updates for Crowds in Houdini 15.5. We begin by baking out 2 animation clips with the Mocap Biped 3 character, populating the scene with crowds, using Paint Density to control our agent placement, projecting those agents to walk on a globe by turning on Enable Terrain Project with Up Attribute, and setting the Adjust Up Vector option to Set to Terrain Normal.
*** Since the making of this video SideFX software has greatly improved it's hair/fur capabilities (specifically from version 16 onwards). While some of the concepts behind the methods shown above might be of some use, it would be remiss not to mention that this is now only here for legacy support. Nevertheless i still hope you enjoy/learn something from the content. ***
Recorded in 1080 for clarity, this is a semi-comprehensive guide to working with Fur in Houdini 13. There have been many questions asked either on od|force or the SESI forums. Hopefully those same questions won't crop up as often as they did.
