This page contains information regarding Telltale textures only.

D3DTX is a proprietary file container format used by the Telltale Tool game engine, storing texture data for their games. Initial beliefs were that Telltale used DDS in all of their games, but after some careful searching that would appear to be false.

D3DTX is the result of importing texture data from various other file formats, like DDS, KTX, PNG, PVR and more. The older (pre-Poker Night 2) D3DTX versions hold all original data from their containers, while later versions extract only the pixel data. The latter would be a useful timesaving feature for artists and developers, who do not want to convert back and forth between files.

Since D3DTX can have texture data from multiple file formats, this technically means it is cross-platform, as long as the original pixel data format is supported on the hardware.

Binary representation (in order of the fields):

After Poker Night 2 D3DTX

  • Usually MSV5 or MSV6 metaheaders (with the exception of Poker Night 2 being MTRE).
  • Stores some filtering options used by meshes.
  • Stores the platform which is made for (unreliable field, does not affect the texture in-game).
  • Stores the name of the file, which is referenced through Lua.
  • Can store the original file name which was used for importing.
  • Stores width, height, depth and array size.
  • Stores the mip count.
  • Stores the image format.
  • Stores the texture layout.
  • Stores some color swizzling data (does not affect the texture in-game, only when it was being imported).
  • Can disable some mips. (Lazy hack used in console editions.)
  • Stores some Engine related data.
  • Can store the original texture data. (Used only twice in Poker Night 2.)

Pre-Poker Night 2 D3DTX

  • Usually MBIN or MTRE metaheaders.
  • Stores some filtering options used by meshes.
  • Stores the name of the file, which is referenced through Lua.
  • Can store the original file name which was used for importing.
  • Stores width, height.
  • Stores the mip count.
  • Stores the ORIGINAL image format value. (For example, DXT1 is shown as DXT1 instead of a number.)
  • Can store multiple texture types.
  • Stores some Engine related data.
  • Stores whole containers inside the D3DTX.
