VTF Explorer

VTF Explorer is a tool for viewing, converting and extracting from GCF files Source textures. It is also capable of viewing, modifying and creating VMT files in GUI. VMT editor is really extensible and itself reminds in some way editing entities properties in Hammer editor.

VTF Explorer itself was written by Vyacheslav "Hoaxer" Dzhura entirely in Borland Delphi 7 except for srcwrapper.dll which manages VTF files through Valve's ImageLoader class to do all the work.
