how do i connect specular color or smoothness map?

[laurentlavigne]

There is no input for those.

I think it’s smoothness * metalmapR = Metallic and metalmapA = smoothness
Speccolor only in specular mode

Hi,

I think you have to change the workflow mode, depending on if you use metallic/specular?

This is how it looks like with Specular, and you get the specular color input.
