What's the secret? If I import my tree – branches unique geo, twigs with leaves packed geo – it displays correctly. If I instance this prim the branches and twigs are separated and I can see only the instanced twigs once, not "attached" to the branches.

How is this done correctly? Also how would nested packed geo work? Like packed leaves on packed twigs?

Nobody???

Should I pack the whole tree (unique branches + packed twigs and leaves) together? Do I need to save it as an .usd file or will a sop import do the trick? Which settings are recommended on the instancer node?

Would appreciate if somebody could share a hint.

Cheers
Tom


P.S.: Instancing unpacked geo doesn't seem to be a problem. Maybe it's much lighter than the tree I'm trying to instance (unpacked 100.000.000 polys).

So far I just achieve results in which the transforms of the packed twigs are all messed up and over the place.

Is this even possible? Instancing geo with packed geo on top of it?

It would probably help to post a hip file of your setup as instancing can get quite involved. It’s unlikely someone will figure out a solution or improvement based on your description. If you can’t share your tree asset maybe replace the leaves with grid/quads of equal face count and scramble the leaf/twig positions so it looks like a random soup of polygons.
