[Request] Dot HACK//G.U. Series 3D Model Format

Post by Rintron »

Howdy, everyone.
I'll get right to the point.
For some time now I've wanted to have a working extractor for 3d models of .hack// series. Particularly G.U.
They are PS2 games, developed by CC2 (who you might know as the developers of the Naruto games, recent JoJo games as well as Asura's Wrath) and G.U has three installments.
There's already a tool that extracts the textures (called hackstract) and can read the files from the CVM archive in which they are stored. But it cannot do much beyond converting textures and extracting raw files.
Each game uses literally same engine, with just tweaks to gameplay. They are kinda like the Telltale episodic games.

Here are some character models (or so I firmly believe), plus a model of a bike.

Additionally there exists a tool which converts 3d models, but it's compatibility is limited. It can, for example, convert the bike correctly (though since the tool is meant for Linux I believe, I had to jump through hurdles to have it compiled under Cygwin) but with character models it barely does anything, if at all.
The source code for that tool is available here:

I can provide more model files, such as the weapons for anybody who would like to take a crack at this format.
I don't care if the converter comes in form of a Noesis plugin/script, Blender script, Maxscript or a standalone tool.
Even if without bones, it would be cool to get the character models (or more if possible) with correct UVs.

So I don't want to bump my own thread or be a nagging asshole.
But I'm just curious if anybody is going to try anything? Just curious.
I realize that the model format is apparently a nightmare to figure out, since there were efforts for it in the past. And everybody gave up.

Its just standard vif tags ps2 uses.

textures look like standard tm2.
you can look at the script for xenosaga should be pretty close format wise.

Thank you for the reply, chrrox.
I took a look at both your script and the one by mario and even tried to use them on the models (purely out of curiosity, as expected they didn't work).
I also took a look at the explanation about vif tags.
Honestly, it all makes my head spin. Ha.
I have little knowledge about how to proceed with all this, but I'll try to figure something out... though I might just eventually come back here, crying and begging for help. Pfft.
Anyway, thanks again. Any help is appreciated.
