Scripting and Reverse Engineering / [FF8] mngrp.bin
« on: 2016-08-15 21:08:55 »
I had a quick look at mngrp.bin and it looks like it contains a bunch of different sections.
All of the sections in mngrp.bin are listed in the mngrphd.bin file in the following format:
DWORD offset //this is +1 from the actual offset
DWORD size

also some of the data appears to be duplicate data from other files, the file looks something like this:

I'll do a bit more digging into the file but it'll probably take a while. If anyone has any other information, feel free to reply :).
There's also a bunch of tim files in there, the names of these are in the exe. e.g. I think 0x13000 is Face_b00/b01.tim and 0x19800 is Gf_big00/01.tim, I'll need to do a bit more looking into this.

Scripting and Reverse Engineering / FF8 Field Models
« on: 2007-08-22 18:16:20 »
I've been having a few issues extracing the data from the field models. I can find the locations of each section of data, I just think that my interpretation of the data is slightly off.
I've been trying to extract the geometry from the d002.mch file, here are the structures I'm using:

struct vertex {
   short x;
   short y;
   short z;
   short unk;

struct TextureMap {
   BYTE u;
   BYTE v;

struct face {
   u32 opcode; 0x07060125 = triangle, 0907012d = Quad
   BYTE unk[8];
   u16 verticies[4]; //vertex id's
   u16 verticies1[4]; //Edge data???
   u32 Vertex_Colours[4];
    TextureMap TextureData[4]; //haven't tested yet
    u32 Padding[3];
   //64 bytes

my understanding of the skeleton is such that I've managed to work out how all the bones fit together and the various lengths and I know that all the vertex offsets are relative to the bones that they are linked with. I can tell that most of what I've extracted seems to be alright since I have a (mostly) intact head of squall and body.

EDIT 1: I've fixed the missing polys issue, it was to do with importing the quads wrong and due to this I've also managed to fix the normals issue just by flipping all the

The issues that I'm having:
      FIXED: I've had trouble with the normals, so I've just duplicated all the polygons with the opposite normals for now.
      FIXED: There appear to be some polygons missing, like a few triangles of the head and body. (I'll upload a screenshot when I find somewhere to upload it)
      The arms and legs appear disjointed and there's a large gap between the body and the arms (I'm guessing this is mostly due to the arrangement of the skeleton  and the orientation of the various limbs). I've managed to reduce the deformation somewhat but it's still slightly messed up.

EDIT: I managed to get the textures working now, although I had to manually scale and flip the coords.

Does anyone with a better understanding of the format have a clue what's going wrong?

I thought there seemed a distict lack of information on FF8 compared to FF7, so today I thought I'd tear apart the FF8 battle models.

Using some information from mirex I've been able to make a program that separates a .dat file into it's different parts.
I've just been looking at the 2 simplist sections to start with, these are:
section 7 - monster data, things like the name of the monster, draw magic, devour info, mug, dops etc are stored here - I've managed to decode a fair chunk of this section.
section 8 - this appears to be some sort of battle script, the only thing I've looked at so far in this section is the dialogue that appears near the end of the file, I've deduced that 0x3F is the start of a dialogue box and 0x3E ends it and I've managed to find some codes that place character names instead.

What I was wondering is if anyone has decoded any of the battle script format because it'd be pretty stupid to waste time on something that's already been done.
