I already made some tools, search for "Falcom 3D texture and model dumps"

I just got a DVD rom of kancolle arcade nu 1.1. idk if you guys are still interested in this topic, but if you don't mind, could you please tell me how to extract a awesome 3d model? can you post samples? Can't really do that because the data is in giant (multiple GB) encrypted .app / .pack files, ...

I took a deeper look into how the encryption works. Basically, the decryption involves two pieces of hardware, which is inside the Sega Nu machine itself and the key chip.Without those two things, you cannot decrypt the data. The decryption combination of the Sega Nu machine and the key chip will al...

I'm interested in this too. I have some experience in reverse engineering.

The issue may be that there may be another plugin installed that conflicts with the .bin extension

Use de4dot.

OpenSora.Viewer can view _X2 and _X3 files.

Sorry for no response for a while. I forgot to enable email subscriptions. The script I made is intended to extract ._X3 files from Sora SC and 3rd. You need moonscript from luarocks installed. Due to the hacky nature of how I extract the files, not all files will be successful in extracting. If you...

Textures have been mapped!!!!

New script at https://gist.github.com/uyjulian/db43b5 ... 00bc78cfdc

I'll make a blender plugin later

Okay, so here's another sample:

The new sample was formatted a bit differently so I adjusted my script.

There appears to be multiple textures in a set of faces, and I have no idea which face goes with which texture. Here's my progress so far: https://gist.github.com/uyjulian/db43b5e19d8dde6af1f8e400bc78cfdc https://imgbomb.com/i/d15/0I47C.png Here's some areas of the mesh area that I can't figure out:...

Anybody know how to map textures?

Thanks!




I think all I need to do is figure out the space between CD3DFile_Mesh and the start of the vertices data.

I'm not that familiar with 3D formats, so I need help to convert model files (._X3) from Sora the 3rd to .obj or .ply files. Here's a ingame screenshot a scene that contains the model: https://i.imgbomb.com/qWUfg.png Another tool, called GameViewer, which is available at https://github.com/prefetchn...
