To create some itresting effects I used program that we have at school called crazybump. You can see bellow difference. On the left is oryginal render and on right with bump map. bump_map crazybump

I recommend everyone to watch this if you are unsure for what is Bump Map : )

If you looking for free bump map generator you may like to check out:  SSbump Generator
I have to see personally how it will work for me : X
