Short description of error
Rendering (Cycles) uses pass index from a linked file instead of the local attribute (when linking a character group etc.).
One can argue it's a feature not a bug as different linked object parts can have different IDs, but that also defeats the purpose of linking, as one has to link different object copies for different scenes.
Exact steps for others to reproduce the error
- Copy both attached files to same folder and open "link-id.blend"
- OR open "link-id.blend" and link a group from "sample.blend"
- Change Pass Index of the linked object to 3 and render. The nodes are set up to show objects with ID==3, yet the linked object does not show in the render.
