Stainless Steel
-
Anyone have a really great stainless steel that they can share? I am looking for something that would be used generally on high end appliances. I seriously have the toughest time making a material like this and I have yet to find something on the web that really gives me this quality.
-
I believe I use one that I got from the Chaosgroup download site. Anisotropy is what gives that nice directional blur...
Edit: hmm, I don't actually know where I got this one, but I don't take credit for it. Here's a sample render. The subdivisions are fairly high, so it takes some time to render with this material.

Thanks Andy!
-
Any chance of getting you to share that map?
-
Her's a couple I had made for myself, hope it helps.

Nice. These will surely add to the realism, especially the second one.
There is also a scratchmap on the Twilight Render forum resources.
The material andybot posted is very close but needs the scratches from the polishing technique. Some more reflection/fresnel would also look better. Saying that it all depends which grade of stainless steel you choose!

Tip:
You can make a stainless steel bumpmap by stretching a noise texture. A scratchmap.
Go to photoshop. Start with a white canvas and Add Noise. Make sure to check Monochrome.
Now apply the rain filter which will stretch your Noise Map. Use Free Transform to stretch it even more.
You can now change the levels/contrast to make the bumps deeper/lighter.
Stainless Steel gets that sheen on its surface from the manufacturing technique....spinning and polishing. Spun stainless ALWAYS has horizontal polish lines (your new bumpmap/scratchmap).
See these old threads of mine, it's twilight render but you will see how the bump makes the sheen and will translate into Vray.

This is where procedural maps come in handy

I took Vicspa's 02 map and adjusted it to be horizontally tileable and make a reflection map from it. Tweaked a few settings from the suggestions here and I think I got something worthwhile. Add bump for closeups and turn down the subdivs to reduce render times.

Nice Valero, any issues with tiling?, I know the pattern does not tile, and I've been meaning to make one that does.
-
offset your texture in photoshop down the middle
you can see seam in the bump -
The problem with that Olishea is that the linear pattern does not match from one side to the other, it's slightly offset, but it can be done with a little more work in PS.

Yes, exactly. You are about to make a horizontally seamless texture.

Here's one that tiles Ok.

For this kind of images this little plugin called "tiler" for PS works pretty well (scroll to the bottom of the page). It works also in an image editor like Xnview for example.

I had already fixed the tiling issue with the vismat I attached.
-
Sorry it must have been subdivisions that gave the texture the appearance of being tiled.
I was gonna upload my own scratchmap, but nobody would learn anything.
Your material is very close, I just believe it needs more reflection to match the photograph you posted. Can you also reduce the blurriness of the reflection in Vray?
Basically, the longer you polish stainless steel; the shinier it gets and the bump is reduced.
So low polish=high bump low shine. High polish=low bump more shine.
It's a very tricky material to achieve....especially as there are so many grades of stainless steel.

Grazie Massimo, I will try it out.
Will also try the plugin just below the tiler one called "Ultimate Artist Aggravator" -
