Material Patina Procedural Process/Texture/Lighting work by Tyrone Marshall
This was a result of an lengthy experiment to create an effect much like the kind we see with those gorgeous detailed Zbrush rendered models.
I am currently tweaking the process. The shader is for use in a project so I will see what I can do to release it in some way. There is no hand painting of any kind. The best use for this technique is that it establishes a good base coat (material) upon which more details such as stains, and discoloration can be added using Bodypaint 3D.
I would be interested in any comments as to how closely this resembles the "patina" effect.

Light and faded patina colors: (The type I am working with).
Ancient, and very time tested!
Another more extreme variety for a different type of look:

Nice project. Seems like fusion would accomplishthe look.
Don't know as I never did a project with a patina before.
Thanks for the link to flickr, great image reference.
I'll be interested to se your progress.

Yes--I think/hope we all know what patina is and how to pronounce it ;)
Thats a nice render--nice effect--but it doesnt feel like its aged and weathered "patina" to me. I think the key is using the dirt/ao shader -- mixed with noise maybe in a layer shader, in either the color or diffuse channel. This way you are getting a secondary color (lime green) into the grooves/corner edges of the model as well as randomly distributed on the surface.
Needs a bit more bump too.
It actually looks like you are doing what I described after another look--but rather than just getting some bump into the edges you need a contrasting color in there too.
Also the lighting of the model makes it hard to distinguish the effect--maybe its the SSS or fresnel or something like that competing with teh weathering.
I'll keep watching--will definitely be a nice shader to have.

OK not patina as such but this is some work i did with fusion some time ago, very easy to setup and i am sure couild be adapted to patina/weathering etc
