Brushed metal texture
Hi,
I’m working on a disk brake. Modelling is finished, and I’m working on lighting and textures right now.I wanted to achieve a realistic radial metal texture. I got close by using a luma shader in the luminance channel for the inside of the disc. Also I’m using HDRI and a few omni lights for reflections only.
However I’m lost for the outside part. The radial/elliptic pattern is similar to what I’m aiming for

Thanks.

I would start by getting the material clean and the way I like it. Then Create a greyscale bitmap in PS with the rotation pattern and layer that into most of the channels… like as a mask on the reflection, specular.

Thanks Randy. I was trying that, but also wondered if there’s a way to achieve it using lumas or some other shader.

the only way I could think of to get that repeating circle pattern would be to use the spline shader with a spline made for the job – which could be done with the built-in tools, a circle spline in a radial cloner for starts.

Hi Brian,
I’m not familiarized with the spline shader. I’ll look into it.
Thanks for the tip -
be careful to read to the bottom of the main page of the help on it. It helps a lot to keep the spline to 100×100 in size and absolutely you have to have the axis like in Illustrator, it should be at the lower left of spline not centered.

ok here is a file with the Nukei Shader I think it will do what your looking for.
Blur the lines between work and play.
