renderpick usage?

I’m trying to figure out how to use the renderpick operator but can’t find any info on it.

I can pick u,vs etc. but I have no info on which geo I’m picking

I have a render top that renders a bunch of geos inside a null and I’d like to know which one I’m picking on the control panel.

Point an Info DAT to the RenderPick CHOP to get the name of the SOP you have picked. Sorry, ya no documentation yet.
