Switch BNTX research

[Random Talking Bush]

Nice to see someone else working on the format and seeing what crap I'm having to go through right now with my own script. I'm pretty much in the same spot swizzling-wise (with non-tiled textures being incorrectly extracted), but allow me to give you a little push in the right direction while I'm getting my own QuickBMS script finished off. Here's a list of the formats I've come across -- the first byte's the actual format, and the second's for the variant:

Code:

0x02XX - R8
0x07XX - B5G6R5
0x09XX - R8G8
0x0AXX - R16
0x0BXX - R8G8B8A8
0x0FXX - R11G11B10
0x14XX - R32
0x1AXX - BC1 / DXT1
0x1BXX - BC2 / DXT3
0x1CXX - BC3 / DXT5
0x1DXX - BC4 / ATI1
0x1EXX - BC5 / ATI2
0x1FXX - BC6H
0x20XX - BC7

0xXX01 - _UNORM
0xXX02 - _SNORM
0xXX05 - _FLOAT
0xXX06 - _UNORM_SRGB
0xXX0A - _UF16

And as for some of the unknowns you have listed:

Code:

Unknown14 = Actually two values. First two bytes I'm trying to figure out (and range from 0-3 and 5), but the second two are the amount of mipmaps (normally 0x01 for UI stuff).
Unknown30 = The amount of "faces" the image has (used for font files and cubemaps).
Unknown5C = Not sure if this is meant to be a long value or just a short, but 0x01 = Default texture, 0x03 = Cubemap, and 0x08 = CubemapFar.

Unknown0C, Unknown64 and Unknown6C (as well as the next four bytes after DataPtrAddress) are always 0 because they're 64-bit offsets.

I'm sure the finished product will be a lot better than anything I'll come up with, so keep it up!
