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!

Thanks working great!
the textures are headerless dxt1 and dxt3 dds with mip maps,
you can guess the image dimension and type based on file size

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:
