VTFx is a file format used by Valve to store textures on the Xbox 360. It has a different header from normal VTF files and stores it's data in a compressed DirectDraw Surface. Conversion or reading from a VTFX file is not possible at this time.
VTFX header
- define VTF_X360_MAJOR_VERSION 0x0360
- define VTF_X360_MINOR_VERSION 8
struct VTFFileHeaderX360_t { char fileTypeString[4]; // VTFX. int version[2]; // version[0].version[1]. int headerSize; unsigned int flags; unsigned short width; // actual width of data in file. unsigned short height; // actual height of data in file. unsigned short depth; // actual depth of data in file. unsigned short numFrames; unsigned short preloadDataSize; // exact size of preload data (may extend into image!). unsigned char mipSkipCount; // used to resconstruct mapping dimensions. unsigned char numResources; Vector reflectivity; // Resides on 16 byte boundary!. float bumpScale; ImageFormat imageFormat; unsigned char lowResImageSample[4]; unsigned int compressedSize;
// *** followed by *** ResourceEntryInfo resources[0]; };
