yeah... but I didn´t want to play more with the material settings. yesterday I made some nice material but didn´t save it :doh:
My problem is always I make a material, look at it in the material preview but when I render it, it looks totally different . And if you finally find a material that looks good and than change anything in the light setup or so it´s totally messed up again .
The surroundings in the material editor render are much brighter than your scene, and that causes the material to look different.
Reflection is going to.. uhm, reflect what it "sees" and in your scene, a large portion of the right side of the entire render is black/very dark. So, the materials looks different (depending on how reflective the material is - in this case its rather reflective) - try adding a light there, to shine the area up, and see how the rims etc will be affected.
Don't use the material sample viewers as absolute references - always test render frequently Lower the rendering quality if you have to.
