... I have done in Rhinoman|AIR in the past?

I try it with the u and v roughness of the metal, but it dosn't work.

It is a basic material for design work.
Strange, if I set u and v to 0.5, than I get a nice blur, but if I use 0.5/0.05, than I see no blurness.

Is this the type of effect you are looking for ?
maxwell plastic + brushed metal colour bitmap !

Did u try to play with the U and V roughness values to simulate that ? or just by using very highres bumpmaps to emulate the scratchyness of such a surface..

it's a .jpg in the plastics colour slot, and that's it !

I think it is a bug.
In my tests as well, there is no perceivable anisotropy using different U and V values (or if it is, then it is not behaving right).

@philipbruton: In your image is no brush effect in the reflection. A brush texture is only a nice fake. U and V Roughness should work, but dosn't do it.
In my Renderman AIR example I have used u and v roughnesses for the reflection and a texture (only random stripes) for the material color. I hope, I can do it with Maxwell too.

this bug was already there in the alpha:

Thank you. Maybe, without extra reflection the fake looks better.

Here I have done an other quick test with the Renderman Renderer AIR in Rhino with GI and HDRI lighting (which I miss very much in Maxwell Beta).

You can use MXI lighting

I have read "MXI is a Maxwell HDR format", but which HDRI formats I can convert to MXI. I have thought, it are only LDR formats.
