  Resource type 0xba856c78, right? Not sure what chunk you are referring to exactly, here is the structure of the file.
  
  

  uint32 mName1 <format=hex>; // "DXT5"
  uint32 mName2 <format=hex>; // "RLES"
  uint16 nWidth;
  uint16 mHeight;
  uint16 mMipCount;
  uint16 mReserved;
  
  uint32 mBlockPositions[6*mMipCount];
  
  local int i=0;
  for(i=0; i<mMipCount; i++)
  {
      FSeek( mBlockPositions[(i*6)+0]);
      uint16 mControlDataStart;
      FSeek( mBlockPositions[(i*6)+1]);
      uint32 mColorData1DataStart;
      FSeek( mBlockPositions[(i*6)+2]);
      uint32 mColorData2DataStart;
      FSeek( mBlockPositions[(i*6)+3]);
      uint16 mAlphaData1DataStart;
      FSeek( mBlockPositions[(i*6)+4]);
      uint16 mAlphaData2PosStart;
      FSeek( mBlockPositions[(i*6)+5]);
      byte mMaskDataPosStart;
  }

  Hi would you please explain the maskData? From my experiment the previous four block data are sufficient to generate the DDS image.

  Those are alpha values used to blend the textures together when compositing the sim texture. Note that this resource is a specular texture.

  Hi would you please explain mast data in details, like how to compute them or it's just a separated image used for alpha threshold masking.
