Now we can go ahead a move on to something that is a different tutorial altogether. Making the banana actually like the wood texture is a part of it. I'm not really going to go in depth into this part. I suggest looking at some of the fine statue making tutorials on the site for more information on this. Once you start playing with this, however, you'll notice how the map really made the texture fit, and made it look very natural.
There you have it. Now, you all have the essence of what displacement maps are and how they work. Remember that this tutorial is just a guideline, and applying it to some images may require a slight alteration of what has been presented. If you have any questions about the things I've talked about here, you can reach me through a site message on worth1000.com. Now, go ye thereforth, and texture stuff.
