metalic materials
I am trying to model a trophy and really want to get some nice refelctions metallic silvers and golds going on in it. I have gotten alright results before by turning up reflection and putting an invisible sphere with a nice gradient around it.
I have gathered some really nice HDRI images though with my new C4D 10.5 tutorials disk and would like todo something maybe with them but I amnt getting great results.
Has anybody got a nice approach to building some cool silver and gold textures.
Cheers,
Brian

There are a couple of things that important for metals:
* unlike other surfaces, reflections in metals are the same color as the metal itself, so be sure to set the appropriate color in the reflection tab. You might also want to colorize your HDRI;
* unless they’re highly polished, metals, like most objects, are more reflective as the surface normal becomes less perpendicular to the camera (fresnel effect). So if it’s a rougher metal, use fresnel in the reflection channel in place of a straight color (but still include the metal color on the dark side of the gradient);
* if you have lighting in your scene in addition to the HDRI, you’ll want to use metallic specular rather than the default plastic. The key there is that you have to turn the height way up (200+) so the object isn’t too dark. Another option is to use the Lumas shader in the color channel.
