VTFedit

VTFEdit is a GUI frontend for the functions contained within VTFLib, an LGPL open source programming library. VTFEdit is a successor to VTFTool and is written by Neil “Jed” Jedrzejewski and Ryan “Nemesis” Gregg.

VTFEdit itself was written solely by Ryan and is a .NET based GUI tool for the creation and conversion of VTF and VMT files. It is a powerful tool allowing files of various formats to be converted to/from VTF format in all of the Source texture formats.

VTFEdit produces MIP maps and DXTn compressed images using nVidia’s nvDXTlib library, offering a wide range of formats and filters.

Other features include the ability to create normal maps from grey scale images, various sharpening filters for MIP Map generation, access to all VTF header flags, a simple tree based VMT creation system with GCF access, a WAD conversion tool, a batch conversion tool and a VMT creation wizard.

The newest version of VTF edit needs some additional runtimes to function properly. You can download them right under the normal download link.
