Hello.
Back in H18.5, LOP Import SOP appears to automatically import primvars into SOP as primitive attributes. However, H19 doesn't seem to behave in similar fashion. Are there now different mechanisms to import primvars as primitive attributes?
Thanks in advance!
LOP Import SOP no longer import primvars?

The LOP Import SOP doesn't import primvars - that happens when unpacking the packed USD prims.
I think in 18.5 there was an odd behaviour where when a packed USD prim was created, if it had a non-boundable type (like Xform) then its primvars were imported as attributes on the packed USD prim. This was a leftover from the original Pixar integration, and didn't support all attribute types and ignored the usual import options like the primvar filter. And, of course, this only happened for certain prim types and made unpacking / transferring those attributes complicated.
This was replaced in 19.0 by an option on Unpack USD to transfer inherited primvars when unpacking.
