I apologise for reviving an old thread, but I'm in a similar situation.
I need to be able to read the "local to world transforms" from several usdprims, and transfer those values to another set of prims via python without going through sops.
I tried using the snippet from the nvidia docs (), but the resulting transforms don't seem to match what houdini displays in the calculated (purple) attributes. Scale is messed up, specially with prims with negative values.
Any ideas?
