Star Ocean Anamnesis Tools

[akderebur]

I have managed to make a working tool for loading the character/monster models. So I have decided to release it with some other tools I have been using.

Decompress ASF (possibly other files too)

Most of the character files use compression type 7 (zstd). You can use this to decompress them : https://www.mediafire.com/file/2spl5lxx ... Dec_U2.rar Drag and drop a folder on to the exe file and it will try to decompress all the files inside.

If your file has a different compression type, you can use this script : http://aluigi.org/bms/slz.bms . Note that both of these methods guess the decryption key, so you might need to decrypt it manually if the program/script fails.

3D Models

Use this tool for loading the models (.asf) and animations (.apk). You need to decompress them before, as described above.



How to use
- Select the model file (.asf) you want to load.
Note : Weapon/prop placement might be wrong. I don't know if I will ever fix it.

- Select the animation file (.apk) you want to load.
- If file contains multiple animations, you will see arrows to go to the next/previous animation.
- Animate Position : Will be unchecked by default. It is easier to preview the animations this way. You can check this before exporting if you need to have position keys in the animation.

- Export GLB: Exports the model in the binary format of GLTF called GLB. There are a bunch of importers for this format. I mainly use Noesis.
- Export NUX: Exports the model to a custom binary format (.nux), intended to be loaded by Noesis. Noesis script for this format : NUX Script

- Export Textures: Exports all the textures inside the asf file in PNG format.

Textures

This tool will extract textures as ktx, from the asf/aif files (as always decompress before) : http://www.mediafire.com/file/6126nmb4w ... SOATex.rar Drag and drop the asf/aif file on to the exe. You can open the extracted ktx with Mali Texture Compression Tool or PVRTextool.

I dropped the support for Bullet Girls. You can try using the old tool for getting some models. Not tested a lot. Download old exporter

SOADec.exe not working for me. I drag cp0101_b01a.asf but nothing happen. Help please.

not work single file. you need drag folder.

3D Models

Use this tool for loading the models from ".asf" files. You need to decompress them before, as described above.

Overview


How to use
- Select the file you want to use with Browse.
- Load : Loads the model
- Load Offset : If the meshes are misaligned with the skeleton try this option instead. For some models the offset is required, for others it is fine with just Load. I will try to figure this out automatically in a future update.
- Export IQE : Exports the model in IQE format. How to open/convert IQE: viewtopic.php?p=138153#p138153

Bonus - Bullet Girls Phantasia (PS Vita)

This game seems to use the same format as SOA. I have made some slight changes to support those files too, but I haven't tried it on lot of files yet. I will try to improve it in the future.



There is room for improvement, and I am planning to work further on this as I have time. Still I wanted to release this version, as it seems to load good amount of character models without a problem.

really great work akderebur.
Some models have UV damage(ex, cc0001_b02a lenath shield and hands), Nevertheless you job really really excellent.
I have one request, you can support manually xor key input?
There are many files that can not be decrypted, cause the keys are different.

[akderebur]

Some models have UV damage(ex, cc0001_b02a lenath shield and hands),

There seems to be bunch of different vertex block types, so the uv offset/type was wrong for some meshes. You can download the updated tool from the link in the first post. It should fix the uv of that char.

Also I have improved the handling of vertex blocks and how skinned/non-skinned meshes are loaded. So more model support overall. Tried it on some monsters and seems fine.

I have one request, you can support manually xor key input?

Yes, I can do that. I will do it some time tomorrow.

I drag cp0101_b01a.asf but nothing happen.

Like einherjar said, drag and drop the folder that has the asf files, on to the exe.

[einherjar007]

Yes, I can do that. I will do it some time tomorrow.

great! can't wait your update.

I could confirm that Lenath shields are repaired, excellent work!
but, I tried [cc0001_b02a.asf, cc0002_b01a.asf] export, they're corrupted UV and Weight of the eye.
cc0001_b02a.asf does incorrect the weight of eyes.
cc0002_b01a.asf had incorrect UV coordinates of the eyes.
I've not tried other files yet, but I think they're have probably the same problems.

[akderebur]

cc0001_b02a.asf does incorrect the weight of eyes.

Incorrect or no weight? Both eye meshes seem to have no weight data, so they are exported as non-skinned.

cc0002_b01a.asf had incorrect UV coordinates of the eyes.

Eyes seem fine to me. Is it not like this with you?


If you encounter another problem send me a pm with a sample file. I didn't get all the files from the game, so I might be missing some.

very sorry, akderebur.
You're right, I'm wrong I used converter is old, wrong output result.

You're definitely a hard worker. If find other problems, will send you a file, Thanks!

thx man ur tools work perfectly , just didnt realize that the model textures of this game is so small and bad compare to the in-game appearance

[akderebur]

I have updated the model tool again, make sure to download the latest version. It should be able to load great deal of monsters or any other skinned mesh now. Also has mesh names too. There might be slight problems with some models still, I will attempt a fix later. I will be busy for a couple of days. Non-skinned stuff like maps/weapons won't load at all probably, but support for those are not high priority.

great! can't wait your update.

I have updated the decompression tool too. Pass the custom xor key as the second parameter and as hex string. Example usage : "SOADec foldername 6361313266633931".

just didnt realize that the model textures of this game is so small and bad compare to the in-game appearance

Yes, there isn't much going on in terms of textures. There aren't even hair textures for characters. It seems like most of the magic is done via shaders in-game.

Can you add an option to output the decompressed buffers to load models not supported b the tool.

[einherjar007]

http://www.mediafire.com/file/dtgmbl6h2 ... e.rar/file

I created a program to move only the decompressed files to "decrypt" folder.
It may be a slow, but I think a it will work until akderebur tool updates.

[akderebur]

Can you add an option to output the decompressed buffers to load models not supported b the tool.

I can do that, but I think it will be better/easier if I post the decompression code. I believe you can already get the index buffers using "addr" tags. After you get the buffer the first integer (2 bytes) is not part of the index list. It is the max step that you should use to decode the high watermark. So you read the first integer as max step, and use the methods below on rest of the buffer.

Code: Select all

List<int> inverse_watermark_transform(List<int> in_inds, int max_step)
{
    List<int> out_inds = new List<int>();

    int hi = max_step - 1;
    foreach (int v in in_inds)
    {
        int decV = hi - v;
        out_inds.Add(decV);
        hi = Mathf.Max(hi, decV + max_step);
    }

    return out_inds;
}

Code: Select all

List<int> unpack_inds(List<int> inds)
{
    List<int> out_inds = new List<int>();

    for (int i = 0; i < inds.Count;)
    {
        int a = inds[i++];
        int b = inds[i++];
        int c = inds[i++];
        out_inds.Add(a); out_inds.Add(b); out_inds.Add(c);

        if (a < b)
        {
            int d = inds[i++];
            out_inds.Add(a); out_inds.Add(d); out_inds.Add(b);
        }
    }

    return out_inds;
}

You pass the max step and the indices to the "inverse_watermark_transform" and get the decoded indices. Then you pass that result to "unpack_inds" and get the decompressed index list.

can you print the result of the inverse_watermark_transform decompression on this example
03 00 01 00 02 00 05 00 02 00 01 00 02 00 05 00 02 00
I just want to make sure I am reading it correctly.
3 should be the max_step?

I won't have access to my computer whole day. I can do it tomorrow.

3 should be the max_step?

If it is the first integer in the buffer then yes, it should be the max step.

[chrrox]

Never mind lol I feel stupid I got it now.

1st decomppression
[1, 2, 0, 3, 5, 6, 4, 7]
then back to triangles
1 2 0
1 3 2
5 6 4
5 7 6
