Metal library

I’ve just started rebuilding my metal materials and thought I would get some of your opinions along the way. I’ll be happy to post the final results.

This batch is mostly the polished and glossy versions. I wanted to get the basics done before fiddling with brushed and aged versions. I didn’t use reflection fall-off for this version. Only tinted reflections

Hmmm… well I’m not sure how much difference this makes, but I desaturated the reflective tint using a fresnel fall-off on the colored metals.

Note:
BRDF - Polished metals use Phong and glossy metals use Ward.

Looks great… aged copper would be green.

It depends… :roll:

Yes. “Aged” is very subjective. Too many variable to take into consideration. By Aged I mean it’s not brand new and has less reflection. Like copper handrails that have had lots of sweaty palms adding just a little tarnish. I guess I was intending these to be used mostly for interior/new construction. I wanted these to be simple fire and forget materials that didn’t need mapping coordinates.

I suppose I’ll need to add another category for Patina. Really aged and weathered exterior metals. Then I’ll have to start using texture maps or maybe procedurals.

an oxyded version… If you understand my french/english :smile:

Looks quite nice, but wouldn’t you better use a more neutral environment in order to judge the right color?

hey, you forgot platinum :!: :lol:

awesome work.

and methral (a LOTR or D&D fan might want to correct my spelling)

OK yeah… that is good… another section… BTW in English you would say “Oxidized”

in English english it would be oxidised :stuck_out_tongue:

I thought this was interesting. A comparison of different BRDF’s and glossiness values for the glossy metal versions.

Same glossiness value, different BRDF

Different glossiness value, different BRDF. This produces a similar fuzz factor between the different BRDF’s.

Originally I was going to use Ward for the glossy metals because it produces a nice satin type finish, but then I remembered this post on the use of BRDF’s. So I guess I’ll switch my shaders and use Phong for the glossy and Ward for the polished. Here are some Phong samples with different glossiness values. I think I’ll go with .5, not quite as focused as .7 and not as fuzzy as .4.

In my French classes back in high school, we used to call it “franglais.” :lol:

on topic -- this is a great way to set up a material library. I might steal the idea and start something similar for our office!

mithril :wink:

bronze too (bronze = copper + tin) , old bronze is patinated.

Looks great dude.

Good way of sorting and comparing them!!

Cant wait to see the final result :wink:

Nice addition, keep posting 8)

That’s not how I understand that thread; it sounds to me like it’s agreed that Ward is best for brushed metal. I don’t see any difference in practice among the BRDFs when gloss is set to 1. I find Ward to be wayyyy better at satin metal than the others, but it’s only really apparent on a big surface like a sink. I couldn’t get phong or blinn to look good at all, but Ward did what I wanted.

looking good.

Only comment I could make that hasnt been mentioned is I remember corten steel being made to intentionally rust. Looks really cool when rusted. Maybee they have a variety of metal finishes and te rusted look is just one of them (I havnt seen anyone here use it since uni )

i like the blinn glossies at 0.7 the best as it seems like a good compromise. ward is just too dulled out. I think you need to crank up the settings a bit though to remove the grain on the glossies
