I am getting this error trying to set keyframes through python in Houdini 20.5. Any workaround?

I need to hide RBD chunks that are moving. I am trying to us the MF_Rigid to do it. It seems like I ought to be able to sample the VAT position UV texture at the top and bottom of a single column to see if the chunks start and end positions are different. I have tried wiring it up, but it's not working. Does anyone have a setup they could share? I tried duplicating the MF_Rigid that is provided by SESI, so that I have 2 of them in my material. I pass 0.0 into the time input of the second MF_Rigid node. I then compare the WorldPositionOffset outputs from both MF_Rigid nodes. This seems to give me distance from the object's pivot, not distance travelled over the whole simulation.

Did the SLERP transforms get ironed out? If not, are VAT 2.0 and VAT 3.0 both available in Houdini 19? We're using H18.5 and Unreal 4.27 now, and looking to install the latest Houdini Engine plugin, which looks like it's intended to be used with H19. Is it safe to upgrade to H19 and the latest Houdini Engine?
