Ye now that's more like it. Multiply that with a low freq noise and there goes the map !

Constant coating layer thickness vs thickness as a function of mean curvature.
I think it gives quite a cool effect, like a varnished child's toy.

Using curvature + noise to blend between two materials - in this case a blue phong and a white diffuse.
The intention here is to do a kind of 'scuffed edges' material.

That one has potential!!!1!
We neeeeed Exporter support for the new stuff, then people would start to play way more with the new stuff!

OK, seriously: how well can that Coating material be used to simulate skin (epidermis, dermis)?!

woooowww, this will make some great dirt materials, is there a way to choose between different blending noises? would also be useful to do weighted curvatures, fe do stronger blend on +y/-y axis for architectural rendering, there you mostly have more scuffed edges faces on showing upwards edges, not the side ones...
hope you get my point, otherwise i can try to make pictures to show

Yes, all that stuff is possible :)
