Gummie, I thought my various platinums were the best, followed by the gold material in the first picture, followed by the gold material you are referring to. I thought it just looked too much like a cell shader. It does have a Maya quality to it though.
The material I uploaded will produce the gold and platinum in the top picture as is, except for making sure the base color is correct. I then produced the platinum in the top, right of the bottom picture with the same material, but with a certain texture in the RENDER:ENVIRONMENT section with ENV.REFLECTION in the material set to ‘100’ and REFLECTION in the material set to ‘0’. I then tried to produce some gold by using ENV.REFLECTION, but I found that this is most easily done if your RENDER:ENVIRONMENT texture looks more like the material you are trying to duplicate. In the case of the platinum material, the texture looked almost exactly like the scene that would be reflected from a polished platinum sphere. I borrowed it from an HDRI site. To do the gold in the bottom left, I started with a base color of yellowish orange, and used the same texture in the RENDER:ENVIRONMENT section, but I used a low setting of about ‘10’ in the ENV.REFLECTION setting of the material, so that the base color would come through. This resulted in what looked like an alloy of platinum and gold. Then I baked the layer with a best render, and used the saturation tool to make it look like it does.
