XRef object with multi/sub material problem

[GabeSZ]

Hello!

I have a little problem when i xref an object with multi/sub material on it.
When i xref it its looks perfect in viewport, but when i render, its look like every object or ID use the first slot in multi/sub.
I attached a test file. If anyone xref it, its looks same? (whole object red in this case)
Tryed other render engines and works perfect, only mess it up in corona.

Thanks for help!

I can confirm this. Looks like a problem with the xref material. Moving to bugs.
