Is the hairprocedural broken in the current daily builds? I get a couple of warnings and errors with the example scene in 19.5.441. The hair isn't visible in Karma even after adding a rest attribute.
Are there any additional steps needed to make the example scene work?

Hi Richard, thanks for the tutorial video on Prism and I wonder when you export the animation by selecting only geo from the rig, how did you keep the hierarchy the same as asset.usd ? File > Export seems always keeping additional parent transform nodes from the rig. Not sure how to drive the shaded asset.usd with that.

You mean you have some additional parent objects at the top of your rig hierarchy, which are not in the asset.usd?
The exported animation doesn't get layered on top of the asset.usd. It get's layered on top of the shot.usd. If your rig requires these parent objects, then you have to modify the hierarchy in your shot.usd file to match that. You'd do that by adding some xforms in your layout scene, where you reference in the asset.usd into your shot hierarchy.

- the animated geometry gets published as anim.usdc and added as a sublayer in the scene.usd, which can be loaded by downstream departments

I am bit confusing this part.
"- the animated geometry gets published as anim.usdc and added as a sublayer in the scene.usd, which can be loaded by downstream departments"
what this means?

Should I use traditional way caching out animated geo as usdc? like file>export>
Or is there other way?

Yes you can save out your animated geometry as .usdc from the file->export menu. Then you have a file, which contains only your animated geometry and nothing else (no shaders, no camera, no props...).
This file can be added now as a new layer in the scene.usd file. In my video that happens automatically in a post-export process. If you are exporting it manually from the file menu, you can layer the scene.usd and the anim.usd in Solaris with 2 sublayer nodes.
