Using an opacity map with the Principled BDSF? I have baked a set of maps in Substance (making trim sheets) and would like to plug them back in in Blender, incl roughness, metal, normals etc. I would like to have those, my base colour map as well as an opacity map. Base colour map and opacity maps are below.




I have seen some solutions (link to other thread) for having a node setup that does not include BDSF, but the outcome is missing all detail from the other maps, see below two image examples. 




I am wanting to achieve the opacity whilst not compromising on the other maps, below is the node set up atm. I have blend mode set to Alpha Blend.




Any help or guidance would be greatly appreciated. Thanks, Ali
If you plug the opacity texture into the alpha socket of the Principled BSDF you should get the desired look.
