First off your gonna need paint shop pro, and you'll need it installed, so if you haven't got it already, check the "What do I Need?" section of this tutorial.  Without this tool, the tutorials aren't going to be doing you much good as it will be what we are going to be using for the tutorial.

The first thing to know about Vampire: The Masquerade's textures is that they are TGA files.  TGA stands for Truevision Targa.  This Images are easy for vampire to use, and change as needed for the various screen resolutions, unlike some of your other image formats that end up looking blocky or copped when resized.  One very important thing with vampire and the TGA format is that the TGA file needs to be a uncompressed 24 bit image.  Most of your gaming engines have no problem decreasing color depth (24 bit to 16 bit) but when it comes to increasing colors your images usually look flat and grainy.

Another File that is used with Textures is a NAM file, NAM stands for Nihilistic Animated Material.  Though this file is not required for textures to work, it does help give the textures some intresting effects within the game itself.  For instance it can be used to make textures double sided so both the front and back of the serface that they are applied to is covered with the same texture.   It Can also be used to hollow images, add slidding effects, and even give your textures motion like the tourch flames.  NAM files in themselves if used right can add more stunning effects to your project aweing people even more.
