Ward Isotropic by Nicholas Breslow


  • Where to find it:


    • Shader Palette / Add New Shader / Choose Diffuse And Specular /


    • NodeGraph / Right Mouse Click / Nodes / Shader Network / Specular




Node Ports



  • Specular Roughness

Maps the "rougness" of the surface.


  • Anisotropy

Maps the Anisotropy. 1.0 = Isotropic.


  • Anisotropy Rotation

Maps the rotation of the anisotropy direction.


Node Properties


Main


  • Specular Roughness

The overall roughness of your surface. Low values give sharper highlights, high values diffuse the specular.


  • Anisotropy

 The parameter sets the ratio between the "width" and the "height" of the highlights, hence when anisotropy is 1.0 there is no anisotropy, i.e. the effect is disabled.


  • Anisotropy Rotation

The rotation of the anisotropy direction. The values are in radian.

The value 0.0 is un-rotated, and the value 1.0 is one full revolution (i.e. 360 degrees)
