Texture Packing

During game format exporting, the process of texture packing converts the artist-friendly material maps into the final game-formatted textures. For example, a common thing to do is have the color and opacity placed into one 4-channel RGBA texture.

The Modeler comes with a number of different texture packers for various engines, depending on which version of the Modeler you are using. You can edit these or even make your own if you need something different.

All texture packers are stored on disk in the <apps install>/texture_packing/ directory. Each one consists of two files: an XML file describing the packer and the output, and a small shader that is run to fill the final textures up using the map information from the materials.
