Crowds - SOP-based Workflow | Cameron White | H20 HIVE

Learn about the new SOP-based crowd motion path tools in Houdini 20. Find out what these motion paths are, take a tour through the new nodes, and explore topics such as combining non-simulated and simulation-based workflow. Next learn how to implement custom tools for manipulating motion paths.

You guys nailed it.

beautiful

Can the crowd simulation to motion path workflow described around 22:19 be used in combination with a crowd motion path transition? Or is it primarily to move paths around? For example to trigger a transition to another cycle post sim. My agents are not respecting this when the motion path uses a simulation as an input, what's the best way to work with this custom pose attribute for a scenario like this?

Great presentation Cameron!

Why is it that when I add a character movement path, no path shows up and the character doesn't move?

[@nilotindoy981]

in Sop to dops crowds, whenever I setup the 'crowdanimated' to 1 the crowds sim in Dops doesn't move, when I Set it up to 0 , dops do it's own things to the crowds and it ownly copy the first frame? what should I do?

The "Ragdoll From MotionPaths" helpcard example has a similar setup you can use as reference. Offhand, I think you might need to set the Crowd Object DOP's "Target Geometry" parameter to point at your animated SOP source

Thank you so much, I'll look for it
