Here is a quick & dirty appearance I put together. Of course you can tweak it to your liking colors, scratches, etc....
It's close but could use a little more adjusting.
You can download the Appearance here: http://dg-digital.com/dl/Zinc-Rainbow-Passivate.zip
What version of your software is it? I'm a 2017. You send me the material file I can not use, drag and drop to the model after no changes. Can you send a screenshot of your adjusted parameters?
thank you Dave Goetsch for sharing your Appearance.
I've copied it into my library, renamed it to .SVAP.
I've learned a lot in defining Appearances from this!
I just added a bump map "Carpet normal" with .5 Bump Strength and be fine!
But now i'm not able to save this back to my library? With the Windows Explorer i allowed me to do this...
I had this some times before ... do you know why?
Okay, i found the answer: According to SPR 1082393 this will be the case, when the palette is undocked! Strange...
