Agent Foot Locking Not Working?

I have an agent driven by mocap that I have baked out. The mocap has sliding feet. I have enabled foot locking on the crowd solver but my agent's feet still slide around. How can I get my feet to remained locked in place? I have specified the foot ball and ankle NULL controllers when I created the agent.

You should inspect the CHOP network that was generated. IIRC it defaults to doing a velocity-based approach for detecting when the feet are planted, which might not be working well in your case if the original mocap has lots of sliding.

Thanks, I am looking into cleaning up the CHOPs a bit with the Filter node in DeSpike mode. I think my posted example is a case of just bad mocap to begin with. I think someone may have bumped the camera or equipment during capture.

Do I need to enable Terrain as well as Foot planting for the overall system to work?

Terrain is optional - you can still have foot planting enabled without it

Good to know.

I think I found one of the main culprits to my foot sliding. The translational scale of the mocap did not match the scale of the rig. Once I dialed that in a bit better my foot locking and overal mocap motion has improved.
