Substance and Modo metallic roughness workflow with V-Ray

[photoindra]

I got several maps from Substance Painter set up for Metallic roughness workflow: BaseColor, Height, Normal, Roughness and Metallic. BaseColor, Height and Normal - no problems. I know where to plug them. Roughness map needs to be inverted and then plugged into Reflection Glossiness.
But where to put Metallic map? And what to put in Reflection color?

You can use the Unreal/Unity materials that come with MODO 10 and later. They should work in V-Ray for MODO, including on the GPU.

Substance Painter should also allow you to export the maps for a non-metallic workflow, for usage with the standard V-Ray Material.
But I don't know the details on that.
