Not a single example file works from this folder. I have tried opening them in Houdini 20.5.578 Py3.11
Most of them have errors on open. Is there something I am doing wrong?

Can someone tell me if I'm understanding wrongly the purpose of these scenes?

You should probably submit a bug report on the main website. I was able to get that scene working by manually installing the required HDA that the error is talking about.

Those HDAs seem to be located in $HFS\packages\viewer_state_demo\otls, simply install them locally inside the HIP.

Thank you very much! I'll try your workaround.
