RecoLove Modding

[AlexWoods]

Example #1 (hide skirt)

 

Example #2 (swap body model with another one)

 

Prerequisites

---------------------------------------------------------

 

• Basic knowledge on Vita with h-encore and NoNpDrm (Please don't ask about henkaku-related questions here.)
• Obviously, retail game card (I used RecoLove Gold Beach in this tutorial.)
• Recolove Model Importer script (and Noesis)
  • https://zenhax.com/viewtopic.php?f=5&t=8004
  • Uncomment line 13 to enable "noesis.logPopup()", then copy fmt_recolove_fed.py into your Noesis/plugins/python/ folder.
• CriPakTools (CPK unpacker and replacer)
  • https://github.com/esperknight/CriPakTools/tree/master/Build
• rePatch reDux0 (for modding game contents in your Vita)
  • https://github.com/dots-tb/rePatch-reDux0/releases

 

1. Hiding some Meshes from a Model

---------------------------------------------------------

 

Unpack CPK file (media/cpk/CharaModel.cpk), you'll get many files like 0000, 0001, ...

CriPakTools.exe CharaModel.cpk ALL

The real filenames are listed in media/afs/CharaModel.als (one filename per one line).

 

In this example, we use Mariana's default costume: mdb_02mar_000_0_S_def_00.fed.
So, rename file 0085 to mdb_02mar_000_0_S_def_00.fed.

 

Load the FED file in Noesis, and find a mesh which you wanna hide.

In this example, we'll hide the skirt mesh.

 

Then load FED file in hex editor.
Goto faceOffset position (570176), and fill data with zero for 2160 bytes (= the number of faces * 6 bytes).

After editing, reload FED file in Noesis to confirm if it works.

 

Replace FED file in CPK using CriPakTools.

CriPakTools.exe CharaModel.cpk 0085 NEW_FED_FILE OUTPUT_CPK_FILE

Put generated CPK file into ux0:rePatch/TITLE_ID/media/cpk/.
Run the game.
 

2. Swapping Two Models

---------------------------------------------------------

First, replace FED file in CharaModel.cpk with desired one.
In this example, we swap Yuina's default costume with Mariana's swimsuit-H.

CriPakTools.exe CharaModel.cpk 0230 mdb_02mar_007_0_G_swH_00.fed OUTPUT_CPK_FILE

And the second, replace TEX file in CharaTex.cpk with right one.

CriPakTools.exe CharaTex.cpk 0499 mdb_02mar_007_0_G_swH_00.tex OUTPUT_CPK_FILE

HINT: You can get TEX files from CharaTex.cpk using the same method as I mentioned above.

awesome

have you found a complete nude model yet?

Sadly, not yet.

Every model has holes inside clothes, like the picture below.

We need to find some methods to edit/add mesh for FED file.

 

[xperiagenerator]

have you searched in the blue ocean version?

Yes, I searched almost all, but it seems that there are no complete nude model, including DLCs.

 

It's possible to edit textures of swimsuits.

But the problem here is that clothes have different reflection color compared to skin, so it looks white.

I guess we need to edit material settings of clothes in FED file.

[nexter513]

is this still going on? i would just follow the instructions to get the nude version of this tho, 0 knowledge on modding.

[AlexWoods]

ya, I'm alive, but still searching for the way to injecting meshes in model.

[oppaimanko]

great mod

i can help you

tell me where normals and uv starts

 

contact me in private if posible

 

Thank you for help! ?

Here is the diff to display normal and UV offsets in Noesis.

i need a screenshot of the model file (fed) opened in hex editor wich highlight vertex,normal,uv

Hi, here is an example of Mariana's swimsuit-H model (mdb_02mar_007_0_G_swH_00.fed).

Any updates on this? I hope this project it's not dead :(

Little update (project is still alive even if its evolving really slow)

progress

managed to import/export model into blender

 

only weight is missing (need more time)

Glad to see this project alive.
Is it possible to edit the mesh, export to the game and play with the edited models?

If it is, can you tell me how to import/export to blender?

[Guest]

A quick research progress

 

1. Vertex Color

The UNKNOWN area means vertex color (RGBA in 4 bytes).

That's why swimsuit looks different than skin does.

 

2. Bone Weight

7th data of FPACMESH: Contains weight groups (bone count, bone ID, weights).

8th data of FPACMESH: Contains maps to associate vertex ID with weight group ID.

[Guest]

 

1. Bake vertex colors into body texture and reset vertex colors to white, so that we have all color info in texture.

2. Change swimsuit's material id to body's one (typically 0). For material id, refer Fig3 of Alex's post.

https://www.loverslab.com/topic/104212-recolove-modding/?do=findComment&comment=2434076

3. Fix normals and UVs of swimsuit.

[Guest]

Imported Honoka body from DOAHDM.

 

 

To add new vertices, it's required to create FPACMESH data block manually.

[Guest]

After thousands hours of researching, I finally figured out data structure.

 

The file consists of header, offsets and data blocks like this.

 

Description using pseudo code:

///// common structure /////
header = {
  char name[8];
  short blockCount;
  byte offsetType;  // 2: int, 6: short
  byte unknown[5];
};

offsets = {
  int offset;  // short if offsetType == 6
  int size;    // short if offsetType == 6
} x blockCount;

// for each offsets, goto (header base address + offset)
block = any data of (size) bytes;

 

///// details of FPACMESH data blocks /////
block[0] = {
  boundingBoxPos1 = { float x, y, z };
  boundingBoxPos2 = { float x, y, z };
  byte meshCount;  // 0: morph, 1: has one mesh, 2: has two meshes
  byte unknown[3];
};

///// if meshCount > 0 /////
block[1] = {
  short _faceCount;  // faceCount = _faceCount / 3
  short materialId;
  byte unknown1[12];
  int vertexCount;
  byte unknown2[12];
  vertices = { float x, y, z } x vertexCount;
  // padding here
  normals = { float x, y, z } x vertexCount;
  // padding here
  vertexColors = { byte R, G, B, A } x vertexCount;
  // padding here
  UVs = { float U, V } x vertexCount;
  // padding here
  faces = { short idx0, idx1, idx2 } x faceCount;
  // padding here
} x meshCount;

// The game uses unique values below
block[2] = {
  uniqVertices = { float x, y, z } x uniqVertexCount;  // uniqVertexCount = size / 12
};
block[3] = {
  uniqNormals = { float x, y, z } x uniqNormalCount;  // uniqNormalCount = size / 12
};
block[4] = {
  uniqVertexColors = { byte R, G, B, A } x uniqVertexCount;
};
block[5] = {
  uniqUVs = { float U, V } x uniqUVCount;  // uniqUVCount = size / 8
};
block[6] = {
  uniqWeights = {
    int boneCount;
    weights = {
      int boneId;
      float weight;
    } x boneCount;
  } x uniqVertexCount;
};

// unique IDs are defined in block[7]
block[7] = {
  short uniqVertexIds[vertexCount];
  short uniqNormalIds[vertexCount];
  short uniqVertexIdsCopy[vertexCount];  // same as uniqVertexIds
  byte unknown[vertexCount];
  byte zeros[vertexCount];
} x meshCount;

// NOTE 1: padding means 16 byte padding
// NOTE 2: all integers should be read as unsigned

How do you edit GXT?

psp2gxt.exe did not work.

[Guest]

@simezi

(1) Make sure that your input format is correct.

Input DDS file should be DXT5 DDS file with no mip-maps (miplevel = 1).

####### Convert PNG to DDS
> texconv -f DXT5 -m 1 -bcdither -y input.png

####### Convert DDS to GXT
> psp2gxt -i input.DDS -o output.gxt

https://vvvv.org/contribution/texconvgui

 

(2) When copying data, ignore the first 0x40 byte header of GXT. Just keep the original header.

 

---

BTW, I found a problem when overwriting FPACMESH.

The cell edges of body turned black. Still finding solution...

 

[simezi]

texture will be disturbed ...

@simezi

You have to convert DDS to GXT.

Any update? After hiding a Meshs, game keep loading endlessly

[PantsuAesthetic]

I was stuck on finding a proper filename after I already extracted the data from CPK leave with the number file, What should I do next?

 

[FrancisBeacon]

Alex, Arc could either of you please make your mods public? I've gotten the swaps to works etc... but I wouldnt know where to begin on editing the textures to get the results you guys have shown.

 

Appreciate it

No plan to share modded files, because I don't have time to respond each specific requests.

 

For getting texture, you can use this Noesis script.

fmt_recolove_textures.py

 

Each *.tex file contains multiple textures for a costume, and you can get texture's address (in hex) and size (in decimal).

 

For editing texture, please see the previous post.

Hello? How can I open the .als file? I'm was worried if this topic or modding scene for this game went radio silent for while... thank you.
