[Xbox] Star Wars: Obi-Wan (*.tx)

Post by Acewell »

This is a old game from 2001. The tx files are uncompressed archives full of textures and it looks like offset info and name table at the end.

I have attached 3 smaller samples for testing
SWObiwan_tx.zip


Thank you for any help! :D

Thanks working great! :D

the textures are headerless dxt1 and dxt3 dds with mip maps,
you can guess the image dimension and type based on file size :D

1 kb = dxt1 ?
2 kb = dxt1 64x32
3 kb = dxt1 64x64
6 kb = dxt1 128x64
8 kb = dxt1 128x128 normal map
11 kb = dxt1 128x128
22 kb = dxt3 256x64 / dxt1 256x128 / dxt3 128x128
32 kb = dxt1 256x256 normal map
43 kb = dxt1 256x256
86 kb = dxt1 256x512
171 kb = dxt1 512x512
512 kb = dxt3 1024x512

edit
i released a Noesis python script here to open *.tx samples:
