@BB
oh yeah, da Teacher has spoken.
Great thanks. rebuilt your andy scene and got good results wit GC 2.2 and IDL
The only thing i couldnt get right was the metallic look of andy with the blinn node .
(post of that simple shader conifg would help, dont laugh about the shadernoob =me)

This comes due to lack of my shader knowledge.
But its not that easy. i think i can read and understand english well.
i can express myself in english so that everbody (maybe with a little smile)
knows what i mean. But when it goes to shaders , it gets more tecnical and complicated for me. Did you ever try to translate expressions like "ambient" "specular", "diffuse"  "AO" ... to german. hah, you need to get a feeling for this translated words.
Didnt find yet  good german tut's that explains basic shaders.

think too, it was a good idea to throw my old GC knowldege away and start from scratch.
I said in one of my former postings, that pp2010 docu about gc is thin. Thats not  right,
the manual explains well, what happens with GC in pp2010. (well it doesnt explain GC in dephts, but that is not the task of the manual.)
funny , now when things getting to work for me, i remember  "the red ball" with Simon and the artisctic lens, "Your lights are to bright". (was my startig point of GC)

@hborre,
following your suggestions with ligths, id did  get good results.
thank you very much
