Well, NeoStrider, of cause you are right that it would be better to look for Maya tutorials. But I was just searching for the man who created the picture of my "realistic modelling thread" in google and i found this tutorial of him. So i´ve read and found out about this function of lightwave 3d and was wondering if something like this is also possible in Maya. As it not semms to be possible, I´ll change my question a bit and ask: "Is something similar possible? Is it possible to create the bump map-effects at some places on your object where you want to?" By the way, NeoStrider, thanks for the link! I´ll have a view on this site
