Delphy's CAS Texture Unitool v1.7
Overview
The following is simply a guide/handbook/manual (however you want to look at it) for the CAS Texture Unitool (CTU). This is not a creation tutorial, so you will not specifically learn how to edit, modify or design textures from reading this.
-
Refer to CTU Tutorials for a list of tutorials. Or, poke around the MTS Sims 3 Creation Forum.
Instead, this will cover the basic features and functions of the CTU and briefly explain what everything means.
CAS Parts
A .caspart file itself can be thought of as a "placeholder" in Create-A-Sim. By linking meshes, textures and other details to the .caspart, you create what is commonly know as a CAS Part. CAS Parts are what a the game actually displays on the sim (i.e. shirts, shoes, watches, etc); this includes the mesh, shape, color, lighting, transparency or anything else that affects the look of the design.
DDS Files
|
A DDS file is a type of raster image, commonly used by many games, including both Sims 2 and Sims 3. DDS files can be saved in a variety of formats, both compressed and uncompressed. You will need to save your images in DDS format for use in the CTU. |
Image Editor
Your everyday run of the mill image editor like MS Paint or Paintbrush will not suffice for TS3 skinning. Instead you'll need a program that at least has these basic features:
- RGB Mode
- Channel View
- Layers
- Image Adjusters (i.e. desaturate, colorize, etc.)
Most people use Adobe Photoshop or Paint Shop Pro. However, there are free alternatives like GIMP 2.0 or Paint.NET 3.36.
Plugin
Many imaging programs do not initially know how to save/handle DDS files, so you'll have to install a plugin for them. Here are two of the most common ones.
DXT Compression Table

| Mask | DXT1 | No* |

| Stencil | DXT1, DXT3, DXT5 | Yes |

* If the mask has 4 pattern regions, then you'll need to include the alpha channel.
