Brushed Aluminium Casing

Tahi · March 10, 2016, 07:45:58 AM

Hey all,

Attached is a couple of images of my casing design (second and third image). I want the Aluminium Brushing and lighting to look a bit more like the
Voodoo Omen Casing (first image) but my Brushes just don't look the same.
I am trying to achieve the vertical brushed look but the lines are too long, and no matter how many adjustments I make I cannot get anything like the Voodoo Omen. I guess both the material, lighting and environment need adjustment or changing.

Can anyone help me out?

Lighting slightly adjusted

Have you tried brushed stainless steel? Might be a better match.

Hey there,

Yes the material is actually brushed stainless, it seems to match the precedent better.

How does this look?

I've found the procedural brushed texture creates strokes that are too long for what you're trying to achieve. The original photo has strokes that are slightly shorter and offset, so they're not perfect.

I have a texture map I used for a similar effect, searching for it now.

Hello Tahi ! You can try creating your own custom brushed texture on photoshop. Maybe you can adjust it to your specific needs. If you google the instructions, you can create it in just a couple of steps with some filters. Hope it helps.

Here's just a quick example using the attached Normal map. I used this on a project where I needed some brushing. You can see the brush strokes are slightly shorter (you can control this in the x & y scaling) and offset. Something that the procedural you're currently using doesn't have. Obviously my example is just a quick one, but I hope this helps!

Ah great thanks for that. It's starting to look a bit more as I expected.

Cool glad I could help, I saw a tutorial online somewhere that shows you how to create this in Photoshop using the Noise filter. I can't find it myself, but I'm hoping the normal map I sent you does the trick, looks like you're getting there!

I find the procedural Brushed node to be quite flexible. You can adjust the X and Y scale independently, the length, the contrast, the colors, and the bump height to achieve some nice brushed materials, IMO. Here is an example material graph network using an Anisotropic material as the base, and separate Brushed nodes, with the same scale and length, but different colors and contrast settings, for the specular and bump. The scale of my example "tower" is 24x24x10.2 inches. The lighting is an HDRI environment with the contrast set to .7 and the brightness set to 1.35. Image brightness 1, gamma 2.2.

That looks great! Nice solve for sure. Thank you for sharing!

Eric that material looks super, well done! Any chance you could upload it to the Cloud Library?

bdesign · March 26, 2016, 11:27:21 AM

Thank you, Richard! Unfortunately, I am experiencing the same Cloud issues discussed in this thread: https://www.keyshot.com/forum/index.php?topic=12010.0.
