(I'll be using Photoshop 7.0, so if you're using GIMP or Paint.NET the screen shots will be different but the concept is the same.) You don't need it, but it's a neat tool for more complicated projects. In addition (but not needed) a channel mask plugin for Paint.NET should be installed.Paint.NET v3.1 and above has a built in DDS plug-in.Adobe Photoshop (purchase), GIMP 2.0 (free), Paint.NET 3.36 (free).I've made this tutorial for beginners and first timers, however, some basic knowledge on how to use your imaging program is needed. Take a look at Basic Mask Editing for that. Take a look at Creating A New Base Texture for that. Teach you how to create new base textures or add transparency.Take a look at HP's Custom Pattern Tutorial for that. Teach you how to make CAS part stencils for the Sims 3.Stencils allow for neat designs to be put on a clothing item, while still allowing the patterns to be customized underneath it. Unlike patterns, stencils do not tile and they are kept in the same spot on the clothing texture. A stencil is another way to customize CAS parts in The Sims 3.
