Hello,
I'm learning the new Houdini 20 SOP-based Crowd workflow, as per this HIVE video.
https://youtu.be/z8Z5PsnWFto?si=jDbCVFfbif7nnkfg [youtu.be]

I have a bird flap clip and bird soar clip as FBX files.
When I try to transition from the flap state to the soar state, the birds shrink to points.
What am I missing?
Thanks

Problem solved.
The default clip in the agent SOP had a different FBX node hierarchy from the other clips.
Here is a quick and dirty test of the bird flap clip transition to a soaring clip.

Yeah, I was just about to reply that there was some sort of scale mismatch between the clips (the other clips looked to be scaled down by an extra factor of 0.01), so an inconsistent hierarchy could explain that.

A belated thanks,
cwhite.
Here is an updated test where I adjusted the speed of the flap clip to better match the soar clip.

I'm loving H20 Crowd SOPs!
