Thanks Thomas,

Does this look correct?:

It seems to render correctly but it does not show in the viewport - is this normal, or should it also show in the viewport? I have v18.5 on a Mac with an inadequate GPU.

I have a reason for using the AO map. It is often used in game engines. In Maya, for example, you can directly feed it in to the material.

How do I use an Ambient Occlusion map with the Principled Shader? There are fields to use PBR maps for Base Color, Normal map, etc, but I don't see one for AO. Or is there a way to multiply the AO map with he Base Color map? If so, how?

I have tried using a Layer Mix node but this blends the maps making the Base Color map less saturated, so it is not the way.
