Thanks a lot for feedback, guys, you are awesome! For those, who want a tutorial - I dont have much time to write some (Im preparing for admission exams for art university - a lot of drawing and stuff… you know), I still dont completly understand how it works (i need more time to tweak parameters and see how they affect another) and its really nothing special. Some details about these materials - I didnt used any photographic reference and textures, only procedural maps, I made models from box, with lots of turbosmooth, noise and multiple displacement modifiers. finaly the material is basic VrayMtl with strong refraction, glossines is about 0.5 and i have used fog, and turned on translucency, and played with parameters. Finally, the postprocess that I have used, made this stuff more interesting - some color corrections and rendered Zdepth pass and used some DOF plugin in afterefects - you can use tha camera blur (in AE CS5.5) or Dof Pro, or other stuff. Again, big thanks for replies, i appreciate it.
