GPU render : Wich Render element to replace VrayWireColor ?

Hi, I’m wondering what render element can easily replace the Vraywirecolor render element. WireColor is incompatible with GPU render.
The Multimat takes ages to setup, so I would like something as easy as wire color.
Thanks

There are a lot of mask channels - Render ID, Mtl ID, Object ID. Have you tried them?

Thanks, yes I figured it out and used ObjectID for now.
