Hi all,

I had again a discussion with a guy regarding the fact that he is modeling for games (Farming Simulator) and in order to save several polys he is not modeling the tread of tires for tractors and trailers but doing that with a displacement map. Unfortunately he is not willing to show me that (if one has such friends the he need no enemies anymore ).
Is there somebody who can show me how to do this? If there is a short video tutorial I would be very happy!

Many thanks in advance for your help.
