Metallic and Roughness workflow Issue

Hi everybody,

I'm familiar that this is a very common topic and has been around for a while. We are trying to get the Albedo, Metallic, Roughness and Normal maps into the Unity standard shader. We tried the standard approach of putting the roughness into the (a)lpha channel of the metallic map, but that doesn't work for us.

We work with Substance Painter and WebGL. We do not want to switch to Universal Render Pipeline because of the amount of work that needs to be done. Is Shader Graph my only option or does anybody know what I might be doing wrong?

Regards,

Niels
