Proxy does not preserve Face ids

I have an object with random face ids per element, and a material that has a multisubtex applied on “Face Material ID” mode. Before proxy its working ok, but after proxy it loses all the face ids. Is it not supported by vrayproxy?

The face IDs should be supported by the proxy. Can you show me a snapshot of your proxy export dialog?

Here you go

It’s because of the “Create multi/sub-object mtl” option. Turn it off and it should be fine.

Thank you!

Vlado, I think that option should be on by default.

Maybe… does anyone else think that? I don’t have a preference either way.
