View Full Version : Bump / Displ. map for brushed metal procedurally ?

05-28-2012, 05:10 AM

still fighting with my brushed metal.
Its about the bump map now. I made a few with all the tools I was able to find (PS, IWF II, FilterForge) but did not liked how they rendered.
Now I am searching for a way to create a map like in the screenshot procedurally. Simple dark lines for bump or displacement and 50% gray as a base. The idea behind it is to be able to change the density and thickness of the lines with parameters to then check how it affects the rendering result.
Unfortunately I can't find a way to do it with nodes. Is it possible at all?

Back in the old days I'd do brushed metal just using the Fractal Noise procedural texture in the Bump stretched long on two axes and very small on the third (depending how my metal was oriented). Circular was tougher needing a morph to really work, but things have come a long way since then. Have a try of Anisotropic stuff...

Preset central doesnt get much love these days - i use it all the time. Check this one (http://www.presetcentral.com/preset/292/) out, if not what you need some quick tweaking might make it so...

Thanks for the tips,
unfortunately the preset uses the same method I used (bitmap). And the plugin for radial noise does not install in LW11 64 bit. Seems to me there is really now way to make a map like in the screenshot procedurally.
But anyway thanks again.

Do you want brushed metal as in brushed aluminum or are you specifically trying to build those shapes with textures/nodes?

If the first, pop this into youtubes search: lightwave anisotropy

If the second, dunno.

Unfortunately the second :-(
