[Question] Dump geometries from an igb file?

Daaamn, this sound difficult :((

 

As I understand may be not many games has possibility to open models from there in 3D-editor, because (it's my dilettante judgement) source files for 3D editor and files that used for rendering 3D models in games are veeeeeeery different. That means that maybe it needs special instrument for opening and converting for 3D-editor and then again, converting models in files for game :)

 

Wooooow. so you made significant progress in this matter! My respect :)

 

Sorry for the late answer :'(
A deviantart user called minmode made a script for Noesis to be able to open and export certain models of the game (all modules [1st / 2nd / Extend] certain items and stages [without animations] and other models). As I understand the script is programmed in Python, I don't know much about programming languages so I wouldn't know how to help you, but maybe you could ask him :'0
Or maybe you can open the script with Notepad ++, I think it might help you understand a bit how .igb files works.

Here is the link of the script in case you need it: https://www.deviantart.com/minmode/art/Update-1-2-Project-Diva-igb-Noesis-Script-752734641

I hope my answer helps you, I barely understand how they work and still have a couple of problems exporting and running certain Custom Modeles that I have made, For example, I don't know how to make the morphs of the hands work (so the hands can grab objects without the game crashing).

 

I'm sorry if your not able to respond, but how were you able to get the animations?

 

Hi :o
Searching on the internet I found a program that allows you to convert .igb files to .mqo (which as I understand is the type of file that Metasequoia uses)
Here is the forum where I found it: https://forum.xentax.com/viewtopic.php?f=16&t=6345

The problem begins from that at the moment it can only convert a single file to .mqo (skin00.igb), which is Miku's body from PjD 1st.
mariokart64n (the one who shared the program in the forum) was able to make a script for 3ds Max that makes a log of almost any .igb file (It is also in the link I sent before xd) in order to understand better the .igb files.

Now going to what is inside the program, there is a file called read_skin00.bat which is the one that converts the .igb to .mqo, I opened it in Notepad ++ and it looks something like this:

Code:

set output="skin00.mqo"
set input1="skin00_head.igb"
set input2="skin00.igb"

bin2mqo.exe mqoHeader %output%
bin2mqo.exe mqoMaterial 1 "髪" "" %output%

At first I didn't understand the structure of the file very well but I found the readme.txt that explains how it works (although it's in Japanese so I had to translate it with my little knowledge of Japanese and the Google translator xD)

Code:

bin2mqo.exe mqoHeader [MQO file path]
bin2mqo.exe mqoMaterial [Material number] [Material name] [Material file path] [MQO file path]
bin2mqo.exe mqoEof [MQO file path]
bin2mqo.exe mqoObject [Object name] [Material number] [Array type] [Number of vertices] [Vertex coordinate address] [Vertex color address] [Texture UV address] [X coordinate] [Y coordinate] [Z coordinate] [IGB file path] [MQO file path]

And I will put some clarifications that I also found in the readme.txt:

[Object name]: The name part of the model that will have when it is extracted and converted to .mqo
[Material number]: In the case of "mqoMaterial" it is used to list the materials and in the case of "mqoObject" it is used to assign a material to each part of the model.
[Array type]: They can be of two types:
0 = Strip
1 = Triangle
(I don't really understand what this means if someone knows please help me with that).
[-Address]: The address to specify in decimal value.
[-Coordinate]: Value to add or subtract from each coordinate.
(I didn't understand this very well either x'd)

And this was what I could find regarding the program and its operation, I hope this can be useful to someone xd
At the moment I don't know how to find the address of the vertex coordinates, as well as the address of the UV texture and the vertex color, so if someone knows how to do it that would help too :o

 

Well, I think nobody analyzed .igb's with Alchemy, because I think only a couple of years ago a version of the program was filtered for the public because I remember that before there were only a couple of people who had the program and those people didn't want to share it (I imagine due to legal issues or something :0)

As for the forum program, well... I think it only extracts the models without bones or anything but I thought maybe it could be useful to someone.
Or at least to have a clearer view of what .igb files are like

But, now that you mention it, I don't think it's useful to us since we have the minmode's script x'D

Oh, by the way, do you know if the animations can be extracted with the stage? I think you told me on Twitter that it was not possible, but analyzing various stages of the game I saw that several had animations but the Noesis script doesn't recognize them :0
I may be wrong, but I was wondering if you knew anything about it xd

 

Oh I almost forgot to answer this message xD
Well, I don't really understand why you need the motions, but in case you need them for some MMD project or something like that you can use the DIVA 2nd/Extend Motion Pack by korenkonder, I think they are all or at least most of the motions of the two games, although you will need Noesis to be able to open the files and also programs like Blender or some other to convert the motion to .vmd



For DIVA 1st you can use the minmode script to extract the motions :o
Although I think that the motions are linked by file (I mean that the motions of the results screen and the song are attached, I don't know how to explain it, sorry UnU)

In case you want to make Custom Motions, for example use Ai Kotoba motion in Edit Mode without having to load several motions well... I can teach you, it's not very difficult :0

But, as I said before I don't understand what you want them for so sorry if I understand something else :'0

 

Aaaaah that tutorial is so bad JHFLKD! It was mine and I didn't think people would see it so I'm going to do an updated version of it!

 

And the reason why I was asking is because the korenkonder motion pack does have most of the motions from 2nd and Extend, but the issue is that some of them are still glitched and he hasn't updated the pack in 10 months...

 

I finished it!!

 

A ._.xD
Sorry, I didn't know that was your tutorial lol xD

Oooh okay :o
Unfortunately I would not know how to help you with that, sorry :'(
I don't have much knowledge about scripting in Noesis :'0

Thank you so much :D
If you want I can delete or edit my post where I show the previous tutorial xD

Oh, and sorry about replying so late x'D

 

Omg no worries, thank you!! Honestly you can keep it how it is, I already updated the desc. of the old video to redirect people. I wish I knew how to script in Noesis too LUL
