A TEXTURE file is an image file saved in a raster image format and is used by Diesel engine games, such as Ballistics, Flatout, Payday: The Heist, and Payday 2. It contains a texture image for an item, character, or environment in the game. TEXTURE files are saved in the same format as .DDS files.

You most likely will not encounter TEXTURE files when playing one of the Diesel engine games. However, if you like to modify gameplay, you can open and edit TEXTURE files to change the appearance of items, characters, and environments in the game. TEXTURE files are not widely supported, which makes viewing and editing them difficult. However, since they are saved in the same format as DDS files, you can simply rename the ".texture" extension to ".dds" and view or edit the texture image as a DDS file. Some programs you can use are XnViewMP, Windows Texture Viewer, and Adobe Photoshop with the NVIDIA DDS plugin. After you are done modifying the file, rename the ".dds" extension to ".texture" and place it back in the appropriate directory.
