Hi, I have a Pop instance piped into pop network. I just mapped a sphere onto to it and I can see it's working in the pop network. But I can't see the sphere is in upper directories.. why is that? Thanks!

It should show up when rendered. If you want them to show in the viewport you need to use a copy sop instead.

COPY SOP! Shoot, of course. Is there any good reason to use the pop instance? Thanks for the reply!

It might have a better performance than packed prims, but I've never tried and compared myself, so I don't know.

I solved this problem with the "Instance Node".
