Dead Rising 2 (PC)

[chrrox]

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.
thanks to help from reveal8n
no weights yet till i figure out the bone pallet.

Edit:
Fix !

wow nice one chrox thanks a lot for what really grateful.

[Kamillho]

Is there any way to make bones work ?

We have a discussion about this awesome tool on the dead rising 2 mod forums.

ryan7259 posted a video on how to do this, I followed the video in the next post with detailed instructions.

I did work on "Dead Rising 2: Off The Record"

Just posting the progress I made with the format. I have meshes, materials, and the rig. but am having problems with all mesh files. I'll need to look more into the vb/ib pairing method the game is using

my goal is to write a model exporter to get new models into dead rising 2 for game modding. although I've hit a snag on the MatTextureInfoArray file. the 2nd LONG has some effect on the textures. and I'm unable to writting valid materials without understanding this section. I'm posting this here in hopes someone will help solve this puzzle piece.

Played DR2 for the first time on the OTR version. LOVED IT!

so had a look at the model format

The game uses a packaging format called BIG, think if it as a replacement for folders that supports compression

BIG FORMAT
--HEADER--
{
LONG : Unknown, Possible File ID / Version ID
LONG : Offset to "RAW Data"
LONG : Total File Size
LONG : File Count
LONG : Offset to "Offset Table"
LONG : Offset to "String Table"
}

--OFFSET_TABLE--
{
LONG : Offset to "Filename", From String Table
LONG : Unknown, Possible File Checksum
LONG : File Size (Compressed)
LONG : File Size (Uncompressed)
LONG : File Offset
LONG : File Type
-- 0x0004 = Info (Header Information)
-- 0x0020 = Data (Geometry)
-- 0x0100 = BIG (BIG Package File)
-- 0x0800 = Compressed Data
LONG : File Compression Flag
-- 0x0000 = File is uncompressed
-- 0x0001 = File is compressed
)

ok so thats old news, but I needed to know that to read a big file. I treat it as a single mesh, rather then unpacking all the files inside. however I'll review the mesh format as if it was decompiled into all its separate component files

....Unfortunately I just have too many unknowns, and there are alot of variables that appear to be hash checks... I can't do any testing because I do not have the game for PC. but rather the xbox360.

would have been kick ass if the format was a bit more flexible and we could import new models into the game!

Anyway this is really as far as I got, hopefully my info can help someone else get a jump start on solving the rest of the format
