TOGETHER BnB: Modding Guide

TOGETHER BnB

https://store.steampowered.com/app/1239020

 

 

TOGETHER BnB includes official nude model for s*x scenes, but it can't be used in story mode.

This guide will tell you how to apply (and edit) nude model for story mode!

 

Please note that this guide is only for mod creators. I won't upload any modded files.

 

Requirements

- Visual Studio Community 2019 (to build custom UE Viewer)

- Blender 2.9 and PSK addon https://github.com/Befzz/blender3d_import_psk_psa
- Asset Editor https://github.com/kaiheilos/Utilities

- Unreal Engine 4.26
- u4pak and Python 3 https://github.com/panzi/u4pak

 

Modding Guide

 

(1) We need a custom build of UE Viewer, to support morphs and normals.

Apply the following diff to the source code of UE Viewer and build it in Visual Studio.

(2) Open character models in UE Viewer, and export them as PSK files.

 

Nana Model Paths:

 - Plain Nude: "/TogetherBNB/Plugins/DLC_R/Content/CH/Clear/Nana/NanaClear.uasset" (recommended to use as modding base model)

 - Complete Nude: "/Game/CH/Nana/R18/NanaR18_F0524.uasset" (more detailed nude of s*x scene. Good for importing only body mesh for editing. Don't use this model as modding base model, because it uses incompatible skeleton.)

 - Default Costume: "/Game/CH/Nana/N_All/NanaF6_2.uasset" (with clothes and accessory)

 

Options (Export Morphs checkbox should be ON only with modding base model):

 

(3) Follow the modding tutorial on Trials of Mana.
https://www.loverslab.com/topic/143609-trials-of-mana-mod-creation-guide/

 

Please read above tutorial and create your new model.

 

You can replace the default costume's uasset, but instead, I recommend you to

create new uasset and specify the new path in NpcClothesTable.uasset (costume list file).

To do this, open "/Game/Character/" in UE Viewer and click "Save packages" from right-click menu.

Then open NpcClothesTable.uasset in Asset Editor, and edit/save it.

For example, to replace swimsuit model with new model, replace two strings.

 - "/Game/CH/Nana/N_All/NanaSwim" to "/Game/CH/Nana/N_All/YourModelName"

 - "NanaSwim" to "YourModelName"

Currently, Asset Editor doesn't show "4.26" in the top-right select box, but it will work without problem.

 

 

 

Modding Result

 

 

 

- Base Model: NanaClear.uasset

- Body Mesh: NanaR18_F0524.uasset (merged into base model, make breasts size smaller to fit Nana, transfered weights from base model)

- Accessory Mesh: NanaF6_2.uasset (merged into base model)

R18 mesh has nipples and gens, so you need to merge meshes by the following method in Blender.

Can you make pubic hair to the gals?

Tutorial above is good, but significant resource seems needed.  If anyone has actually run through tutorial, would love for someone to share an actual mod.  Sharing a typical how-to is one thing, but one that requires all those programs is different (but I do appreciate the share, and am debating possibly trying, but lots of things to track down to even begin). A story mode regular nude mod would be great, the models look fantastic (why it's not included is beyond me, perhaps eventually).  Or if anyone has actually tracked down a mod on a chinese forum (I only say that as the discussion forum for this game in steam is all chinese).  If I find anything, I'll share. 

[Volcannon08]

It would me much simpler if we could just install a mod that did all this for us?

 

P.S. Also why is this proccess so complicated?

Please share the nude models

Nude mod for this game would be nice.  But if not, play this game instead, it has super real graphics and nude models included in:

That's what i've used once, worked great.

This game has fully interactive sex scenes with detailed nude models already.  It shouldn't be hard to remove clothes in game?

I tried everything, replaced all the lines with Nana suits with the version of the R18 model, nothing changes in the game. I tried just to put the archive in pak or in the ~ mod folder. Checked through umodel, the archive is read and the file appears where necessary. In general, nothing works. It may not work anymore in newer builds. Does anyone have a 100% working version of the mod?

Do you have any modified umodels? I don't know how to compile umodel source code, so I lost facial morphs when making mods. Can you upload it if you have one

no, I didn't touch the models at all, I just tried to change the default model to the R18 model via cloth data...
