Thanx Mike for you help.I tried Kerkythea before yafaray and cycles,particularly when worked with 3ds max several years ago.I'm sticking with yafaray rendering plugin for blender cause it is pretty fast and gives me nice and almost realistic results.I downloaded Kerkythea and maybe I will try in the future to learn it.New blender cycles is also pretty realistic rendering engine.It works nice with my coreI3 processor.Here is my render test of my gillette razor mach3 in blender3d and yafaray 0.1.2.I used hdr image for the background and 2 area lamps as a light source.I see I have to change something in moi on my 3d model around the neck something looks wrong,but I will try to fix it.Thanx again for your valuable advices.
