Ah, thanks very much John. I figured I must be missing a trick.

Cheers,
Andy

To reference the current geometry you can just choose "Myself" or "Myself (No Reads from Outputs)" if you're not reading the same attributes you're outputting.

Using an op: syntax with the "File" option doesn't seem to make a lot of sense, as I'm within POPs and I need to pull the geometry data from the DOP simulation, not from a SOP. The "First Input" option etc. doesn't seem to make sense either in this POP VOP context.
