0x9C offset 20 00 00 00 00 00 00 20 at this position starts the texture part in the raw file (PC only)
0xA0 offset 00 00 00 00 unused at this position starts the texture part in the sep file (Mac and PC demo only)
0xA4 char[28] AD DE dead unused


Below you can see the pictures for this example. The first picture shows how it's stored in Oni, the second how you see it in the game.
