  • I need help creating anisotropy in V-Ray Rhino

    So I need to make it look like the bottom of this pan. I tried making a spherical map, but that didn't work. I make a brushed aluminum texture and applied a reflection layer to it and I set the anisotropy to -1, but it didn't do anything. Also, will anisotropy change the brush from straight to round?

    You need a map like this planar mapped to upper disk surface. This turns the UV from 0°...360° dependent from the brightness. And additional best you use a polar brush texture like attached.

    An other way is to use a linear brush material and apply a spherical mapping placed below the button object or create a new button based on a rotated profil (than simple surface mapping can be used).

      What Micha wrote should suffice.
      For the first part - reflection Anisotropy of -0.8 and a Gradient texture (Preset: Black & White, Type: Radial, Interpolation: Smooth) in the Rotation map slot can also be used.
