I've got something very difficult here:

GTArcade might have some of the best models I've seen, but when I try to get them, I face several problems. I've got no idea about working tools, where the files with the models are located and if the version makes any difference... I'm mostly focused on League of Angels III, since I play this game and wishing to get those models. If the problems are packed in questions, these are:
Do some extraction tools for GTArcade games (on PC!) exist?
Where are the files from the games located?
Which platform is better to work with when extracting?

For now, I want to get a closer look on what these models look like outside their "natural" environment - any help with that is appreciated

Check this directory on your PC for LOA3 files:
\\ Change "YOUR ACCOUNT" to your user account, also I used the GTArcade version, not the browser version;
C:\Users\"YOUR ACCOUNT"\AppData\Local\Gtarcade\plugin\air\main

\\ These contain an ATF header
.DXT files are your textures
.BA files are your models

These files are located in the Assets/xx/xx/xx/.. folder mate. This is as far as I can help you regarding League Of Angels 3, sorry and good luck.

This location guide is already nice and I found the files for myself, but... There's the old problem with file formats again... Is there a program which can open .dxt and .ba files without a problem? I tried the guide on the linked site and AssetStudio doesn't load a file

Glad it helped. GoT-WiC is built on the Unity engine, so AssetStudio works with it. LOA3 uses a different engine mate, sorry. I had a look and couldn't find any tools sorry. You might have to upload some samples and request someone with the skills to have a look at them.

Now's the time for the final step before I can take over... I finally got the real model files out of the double-archived thing and now I'm searching for a program and/or script for either Blender and/or Noesis to open up the files... The zipped file is hosted here. Does anyone know of scripts to open them/a program that opens them and is free to use? The models here come ultimately in .s3d format, something that got introduced waaaay back in 1999 (I'm surprised by that as well) with the game Everquest...

Also, I just can't figure out where I'd have to start in the files for creating the script to import them in Blender or Noesis... Is there any file engineering expert somewhere?

The files specify that a "s3dMesh" is packed in each of them - it seems that this is something that makes the model ripping really difficult to get done. And with that, there came another thought to my mind: I do think the .s3d files on this one are some kind of dazzler. Why? The appear to be another archive file (in formatting of EverQuest), but they aren't an archive. What's the true file extension to them?

What does that mean? I'm not seeing clearly through that sentence...

It means that I have to do further tests. (There's an unexpected/superfluous counter in the face indices data which I eliminated. But it didn't help to display a proper mesh. Point cloud of uv data seems to be "ok" as can be seen.)

Looks OK to me.

That program there looks interesting - where did you get that?

Also it's nice to see some hints on what the model looks like - if the textures aren't a problem as well, then I can collect the tools I need to get this done

See the 2nd link in my signature.

There's no way you can get the mesh without coding a script or something.

I'm well aware of that, but unfortunately, I'm lacking said script... Is there any for this specific file format?

Posted: **Wed Aug 28, 2019 9:03 am**

Here's the Noesis script for the test. No guarantee that it'll work with all files.

Obfuscation at it's best - there's only few people who could have solved this riddle, congratz!

Offset = blockStart + PositionIdx*0x18 + 0xC

(Where PositionIDx is really crazy:)

For role_m_000.s3d more fiddling to be required:

Obfuscation, is it? I thought it was just some old game format.

The PositionIdx is the index of the first vertex in a vertex weight group, followed by an int32 weight count. What doesn't make sense is that though the weights add up to 1.0, some skinned to non-zero bone ID are of zero weighted, why bother to store such info if they're weightless?

Yeah, I noticed that too. But based on the UV, shouldn't it be some kind of body part instead of a boot? I have a couple of theories of getting the actual positions: 1. calculate the average position coordinates in a vertex weight set, or their weighted average; 2. take the coordinates with the largest weight as the position of this vertex. But I don't have time to test it now.
