I just recommend this [http://www.photoshoptextures.com/texture-tutorials/seamless-textures.htm Tutorial]

=How to import an existing Model in Blender?=

* First of all download the [http://www.ogre3d.org/tikiwiki/OgreXmlConverter OgreXMLConverter] and put them in one folder. 
* Download the older [http://download.blender.org/release/Blender2.49b/ Blender version 2.49b] While installing please choose "use the installation directory". Install it in a seperate folder becauseyou only need this installation in order to import the meshes.
* Get [http://www.python.org/download/releases/2.6.6/ Python 2.66] 
* Go to the [http://code.google.com/p/torchlight-to-blender/ Ogre Mesh Importer]and download the script from the "Downloads" section. Unzip the file into your .blender\scripts\ folder. Now inside the script look for line 61 and there place the path to your OgreXmlConverter "ogreXMLConverter = "X:\OgreXmlConverterfolder\OgreXmlConverter.exe -q""
*Import the Mesh in your Blender 2.49b and save it as a Blender file
*Install in a different folder the newest version of Blender and work with the newest Blender by opening the Blender file with the newest version.
*In this screen you can see how to get the model and the texture included. In terms of texture. Don't use the Material/Texture section but the UV-mapping one and put the screen with the wireframe into Edit Mode. Then you will see the polygons in your UV Map which you have opened in a second screen. Push the image button in order to load the texture image.

*Now it is quite easy to work with it or just export it for other 3d programmes.
