OniUnPacker

OniUnPacker (or OUP)

Not much implemented in OUP until now. Features in 0.13a:

• Read Oni's data, view the data of the files in the dat
• Extract Oni's data (but the extract-format will be changed later)
• Preview TXMPs (textures), TXANs (texture animations), TXMBs (big image maps (as far as I know they are only used for the intro/outro splashscreens and the backgrounds in the menus))
• Replace TXMPs with normal 24bit bitmap-files (and TXMPs are converted to this format while extracting too)

Example of replaced textures (replaced all of the fire*-textures in level4/airport assault with an test-bitmap and set transparency to 1):
