Instead of putting roughness 30 to 2nd layer, can you try making it lambert and mapping it with the same map but a version with %30 grey instead of white. It should work like you want.

Thanks, I'll give it a try.

...just did a small test:

AndreD, your file is 3 layers.

nice!

but it doesn't seem to give the result I was looking for;

the 'holes' seem to have retained some reflection and the solid area doesn't have the shine I was looking for.

Oh, now I understand why you failed because I forgot to mention you need to use invert of the same map for weight.
