DAZ to Blender Metal Maps?

Fugazi1968

Afternoon All

Loving the new version, just one question.

When I send a prop over to Blender, it takes the roughness, color and normal over but not the metal map.  I've tried it on several of my props and none work.

Just wondered if this is happening with anyone else?

Is it possible that the image map is DS needs to conform to some sort of naming convention, which the others do but the metal doesn't?

Thanks
