Per-face material mapping does not copy. HELP

Hey

Just spend hours on material-mapping an entire part library with per-face material mapping: Plywood edges and plywood surfaces. Everything looks great, but when I copy the parts into a new rhino file, the edge (per face-mapping) material is not copied. So the part gets the birch surface material on all edges.
Very frustrating.
The materials with bitmap textures are in the file, so it is not because the materials are not linked. They have exactly the same material library.

I really need a solution for this.

Hello- can you post a simple example - just a box - of how you have this arranged?

Hello- thanks, sorry, my request was not clear -I meant a 3dm file…

This :slight_smile:

I used ctrl + shift + click for applying the materials within the block (so no explode as I need it to be joined)

I confess I am stumped - I do not see any texture, material, or mapping that accounts (to me, anyway) for the edges…
