I am using Houdini 20.5.27 and trying to apply Ragdoll to a prop (e.g., a ball) following the exact steps from the Animation Workshop 12 | Ragdoll | Props tutorial.(https://www.youtube.com/watch?v=1JVgi_9Q7ho) However, I am encountering several issues:

1. When switching to Ragdoll Mode in Animate Mode, Houdini does not automatically generate a .ragdoll controller for my prop.
2. The "Active" checkbox in the Ragdoll settings cannot be enabled, preventing the simulation from running.
3. I have ensured that the prop is selected correctly before entering Ragdoll Mode.
4. The tutorial shows the process working seamlessly, but in my case, nothing happens when switching to Ragdoll Mode.
5. There are no apparent error messages or warnings in Houdini’s console.

Is there an additional setting I might be missing in Houdini 20.5.27 that prevents the Ragdoll system from working on props? Have there been any changes in this version that require a different workflow compared to the tutorial? Any troubleshooting suggestions would be greatly appreciated.

You surely don't mean 20.5.27?

Make sure you're using at least 20.5.326
