VTFTool

VTFTool by wunderboy, currently in ongoing development, is a windows replacement for several command line tools for handling the new Valve Texture format. Like VTF2TGA, it can take a VFT file or folder of files, and convert them back into TGA format for editing. You can also export all the MIP images for a texutre, plus export a TXT file which contains the config settings for re-compiling the TGA back into VTF format. It can also convert TGA files into VTF format and create a basic VMT shader file for your texture.
