looks like the header is xored with the alphabit or something like ABCDEFGHIJKLMNOPQRSTUVWXYZ
but thats not needed for these files just run offzip on them and you get the decompressed files.

I don't understand what the problem is in my script i convert the uv's so they are one uv per vert.

Here is an updated script weights are not perfect yet i have a few ideas on this to try.
Also it now imports all of the type 6 mesh not just the first part.

I have worked with this before this is how you do it.

league of legends was just like this format.

most formats export the bones in order
so you just convert the bones as you go and store those bones in an array then when you read a bone you just get its parent id and point it to that index in the array.
its a lot easier to know with what file your looking at.

ill make a bms for this game soon wont be too hard.

Dead Rising 2 Model Loader.
Extract the .big file so you get the geo files then run this script on that folder and it will import them all.

yeah sure i don't know why that guy said there were 2 encrypt ions it was just xored with a compressed header.

offzip is only zlib

your best bet is to run it on the emulator then dump some files from the emulator.
then you can compare the files or if your lucky you can just rip them all from there.

sxm = .x sxb = .bmp uep = .png you have to xor it with the key 3547FAAD then the file needs to be byte swapped so if the file went 1 2 3 4 it needs to be swapped to 3 4 1 2 sxb files use the key 74781954 and also need the swap uep files use the key D92C5B00 sxm files use the key 8A217D2E swap bms ge...

I got the model format figured out but not the material section. without knowing the material section i cant get to the data i need to import.
The only way i can import models is by specifying the offset and that is to complex for people to do on their own to use my script.

I think he posted different files or a different section of the file the files you post are just filled with 00
