Weathered antique bronze or copper patina shader?

Ptrope

Is there a shader package available to replicate the overall green patina of an outdoor copper or bronze statue, one that includes the normal streaking, discoloration, and variations of surface from rough to polished? Is it possible for an Iray shader to exhibit a combination of these textures and colors based on the angle of incidence? I know there are irridescent shaders taht do - just wondering if something like this is possible on an antique surface. All the 'antique metals' shader sets I find seem to fit in the "museum quality, well cared-for, polished and dusted regularly" variety.

Would any of these work? https://www.daz3d.com/old-metal-shaders

Or there are these for 3DL: https://www.daz3d.com/daz-studio-dirt-shaders

The dirt shaders are exactly the look I want, but it says these are only for 3delight - I need Iray.

There are also some iray patina shaders in this set: https://www.daz3d.com/4k-metal-shader-presets-1-for-iray?cjref=1&utm_source=cj&utm_medium=affiliate&cjevent=c11aa938ad4211ea821601210a240612

You might also consider rendering your statue in 3DL and either create a billboard to use in your scene or render the rest of the scene seperately and then combine the two renders in PhotoShop or GIMP.

I'm not sure if these will work for you, but as they are free you could at least try them. Will (Oso3d in the store here) put up some freebies a couple of years ago - read about them here: https://www.daz3d.com/forums/discussion/comment/2014636/#Comment_2014636 and here: https://www.daz3d.com/forums/discussion/comment/2325576/#Comment_2325576

He has sets of procedural Iray shaders free here: https://www.sharecg.com/pf/full_uploads.php?pf_user_name=wtimmins - the one he mentions is in the third set (WTP3).

Thanks, MelanieL - I'll check those out . 3anson, those are ones that I'd pretty much written off, based on the previews - nothing there looks weathered, but since the second one is on sale for $3.99, I don't have much to loose by tring them .
