Hi and Welcome Zamolet.
It looks like the material you're looking for is not bronze but brass

Hi! yes i think brass is more properly. sorry about my ignorance but do you know where the nk data codes are? i've been looking for them but haven't found

@zamolet
Check into your Indigo directory. Nk files are in "nkdata" folder.

Kram: Dunno if coloured specular highlights are physically acurate (I can't think why not) but they're damn handy for carpaints...

There was a "(?)"

Setting highlights color by hand is of course not physically accurate. Indeed one property of metals is such effect; nk data is fine for that.

if the nk libary was full featured, at least.... some things are missing:
Iron / Steel, Brass and bronze and many more

Then, you could have a big glas libary and gems and such

the nk could be far more detailed, I'd say^^

I'd settle for being able to find my list of what the nk materials in the current library are, I can remember some of the basic elements from school chemistry, but not all of them...

I know the old user manual with them is lurking in a zip file somewhere on my HD.....

Not really what you may have somewhere on your hard drive but still in topic of nk files. At least here is your colored highlight

ah and if you use tinmans nk convertor, I've a photoshop idea for you

find some pics, where the mat looks as you want it and the environment is leveled and white balanced correctly

use the colourpicker (with big radius) on a shiny piece of bronze/brass (what ever you need, now) and copy + paste the values that you get in tinmans prog

you should pick from a well exposured perfectish looking part without shadows or highlights

If you're patient enough, you also can pick a colour of a not overexposured reflection and use the reflection side of that nk (see other post) with the colour side of the other one

personally i think you can use another renderer like povray or blender for non much reallistic effects like alien artifacts and spaceships also you save a lot of time

but thats only my opinion

well they look like crap though....

plus I want it look surreal photorealistic - kinda like a what-if this was real what would it look like if I photographed it

yeah, that would be interesting, indeed

If you have an idea of how mystic metals look like, you can also build them with the correct colour

- I wonder if (if Tinman can be seen, anywhere) if he can make it with two colours - one for reflections and one for "diffuse"

- would even be interesting for some SSS effects, if both values are put out

you use one as scattering colour and the other one as absorbtion

and if you find a third value, somewhere, you could use that as henhey-greystein
