Thanks, guys. I used Copy Stamp in the end.

I am using Houdini 16.0.608 and I see that the Copy and Transform SOP does not have the “Transform Cumulative” option that is mentioned in the docs. Has any one else noticed that? Is it a bug?

I got this error again and filed a bug report. I am posting Support's answer here in case someone else gets the same error messages:

This is because the .hip file contains an entry in OPpreferences for Shop/vopmaterial which is not an HDA

To see that, open Window > Hscript Textport and do ‘otprefer’.

To clear the error from the scene do ‘otprefer -c’. See ‘help otprefer’ for more info.

This indeed got rid of the error, although I am still not quite sure what I did to cause it.
