HI,
I am kind of new to Houdini. I am facing this weird issue as I have imported an alembic asset(renderman's rolling pot asset) through file node and wanted to assign different material to its individual parts. So I have taken group node and added those parts in Base Group and named the asset part in Group Name section. Later I have taken a material node and created few materials and assigned them but nothing is getting applied on the geometry.

Please help me with this..

Let me know if you need more data.

Regards
Devank

I might guess you'd have to Unpack the alembic before you can assign materials. Otherwise, you'll just be adding attributes to the points representing the packed parts, and not the actual surface.

Try dropping down an Unpack node right after the file or alembic node.

Actually i did that but getting "/polygons: out-of-range shader index" error

Can you share your HIP file + the Alembic file? Also which render engine are you trying to use?
