For a material (color closure) shader, create a:.

OSL shaders are supported only in V-Ray Advanced and not in V-Ray GPU. V-Ray for 3ds max supports compiling and rendering OSL shaders,Īnd also offers some handy shaders for download on the V-Ray documentation website. More info about the VRayMtl Metalness parameter Note that in this example we use Anisotropic Rotation values of 0, 8, 16, but this may change with different roughness and anisotropy values.įor the materials Diffuse Color property we set levels that will combine to create the general brightness and tint of the metal, and the materials Reflection Color is set to 100% so they will combine to pure white reflection at grazing view angle.įor example, if you want the general metallic color to be a yellow RGB: 255, 186, 57, than the first red metallic component material would have a Diffuse Color of 255,0,0, the second green metallic component material would have a Diffuse Color of 0,186,0, and the third material, that adds the blue metallic component would have a Diffuse color of 0,0,57, so the combined blend will have the desired general color. The additive combination creates an anisotropic reflection that “spreads” the color of the spectrum. Use a VRayBlendMtl to additively combine 3 anisotropic metallic materials,Įach of which reflects a pure primary RGB color, but has a slightly different anisotropic angle.

This technique can also be implemented in V-Ray for other 3D software like V-Ray for Maya etc. This material setup is using V-Ray 5, but will also work for V-Ray next,Īnd in previous versions, not having the Metallic property, it can be implemented by unchecking Fresnel Reflections and setting the color through the Reflection color.
