creating rpoxies straight with multi mat.

It there any hope that when creating proxy it will also make proper multi material for it?

The V-Ray manual:
Materials are not saved in the .vrmesh file. Instead, the geometry will be rendered with the material applied to the VRayProxy object. This is because third party materials and procedural textures would be difficult to describe in a general way. In addition, you may want to edit the material independently of the mesh.

As far as I can understand your wish, you want the material to be stored in the proxy ???

I did a proxy scene last week with 3 IDs on the Mesh... There were
absolutely No problems rendering it, as the Mesh stores that kind of info, like
the IDs... so all You need is just to have your material (in the scene) and then apply it over the proxy...

yes, but thgis mat has to be multi material. And what if I got many different materials. I would like when saving proxy that it will create mulit material with all material used in model.
