Want to follow along but don’t have a license?:  The following chart provides Diffuse and Reflection Color values that help you create realistic metallic shaders with V-Ray for Houdini: Name Base (diffuse) color Reflection color Metalness Base color (web) Reflection color (web)   Red Green Blue Red Green Blue Silver 0.996078 0.996078 0.992157 1 1 1 1 fefefd ffffff Gold 0.984314 0.901961 0.670588 1 0.980392 0.764706 1 fbe6ab fffac3 Copper 0.972549 0.811765 0.760784 0.996078 0.905882 0.847059 1 f8cfc2 fee7d8 Aluminium 0.960784 0.964706 0.964706 0.960784 0.980392 0.988235 1 f5f6f6 f5fafc Chromium 0.772549 0.772549 0.772549 0.568627 0.556863 0.690196 1 c5c5c5 918eb0 Lead 0.831373 0.831373 0.85098 0.74902 0.752941 0.819608 1 d4d5d9 bfc0d1 Platinum 0.980392 0.972549 0.933333 0.996078 0.992157 0.976471 1 faf8ee fefdf9 Titanium 0.988235 0.976471 0.917647 0.996078 0.996078 0.980392 1 fcf9ea fefefa Tungsten 0.968627 0.92549 0.886275 0.984314 0.945098 0.854902 1 f7ece2 fbf1da Iron 0.952941 0.945098 0.921569 0.94902 0.960784 0.956863 1 f3f1eb f2f5f4 Vanadium 0.980392 0.952941 0.898039 0.996078 0.984314 0.94902 1 faf3e5 fefbf2 Zinc 0.945098 0.941176 0.937255 0.960784 0.968627 0.976471 1 f1f0ef f5f7f9 Nickel 0.952941 0.937255 0.886275 0.960784 0.960784 0.929412 1 f3efe2 f5f5ed Mercury 0.898039 0.898039 0.898039 0.878431 0.909804 0.941176 1 e5e5e5 e0e8f0 Cobalt 0.847059 0.831373 0.811765 0.803922 0.803922 0.815686 1 d8d4cf cdcdd0 *The RGB values are relative representations. For a better result, use the hex (web) codes from the table. To download scene files:  The Index of Refraction (IOR) plays an important role when creating a physically based material and has to be considered as part of the shader. For metallic materials (having Metalness value of 1) it is automatically calculated from the Diffuse and Reflection colors: see the  Artist Friendly Metallic Fresnel  paper. For materials with Metalness < 1, the Fresnel IOR parameter from the interface is taken into account. The site  RefractiveIndex.info  is a great resource for understanding the proper IOR of different materials. Useful information on metallic surfaces can be found at the  Journal of Computer Graphics Techniques  site. For detailed information on the Metalness parameter, go to  Understanding Metalness  Chaos blog post. Examples Below are some examples and their settings.
