== TEX Texture Data Format for PC by [[User:Mirix|Mirix]] ==
FF7 PC texture consists of header, an optional palette and bitmap data. Usually data are stored like palletized picture, with bitmap pixels referencing to palette. Color 0 (in palette its usually black) is usually used as transparent color.
Sometimes, (I'm not sure if it is used in ff7 at all), when bit depth is 16 data are stored as packed RGB in style RGB555, which means 5 bits per color in one 2 byte entry.
