Need Help Viewing models from Akiba's Trip from Steam

[Jarten]

I'm pretty new to exporting models from games and I was hoping to extract the character models from this game in order to see how they were done clothing and hairwise, and to find out if it was possible to create newer textures for them to put back in game. By any chance would anyone know how to view and possible convert .pepd model files for editing?

Also I just joined this site so if I posted this in the wrong area or something please let me know so I can fix it if I can.

welcome to the forum, Jarten.
On a quick glance I found this:
viewtopic.php?f=10&t=10941&p=102489&hil ... pd#p102489
but it's for PS3 and Akiba's Trip 2

Keep in mind: other than PC files (little endian) the ones from PS3 are big-endian.
So even if the model format didn't change from AT to AT2 the noesis script won't load them.
(But maybe help create a new script? A pepd model sample (PC) would be needed, though.)

Thank you for having me

Well, from looking at the game I think its a port of Akiba's Trip 2.
I managed to find an extractor to get to the model files so I was able to copy the model files and other ones out of the main directory.
Then I did try the noesis script that was in the link you posted but it didn't seem to work when I tried to follow what was directed.

here is one of the model files altho I don't know if it will need anything else to go with it.

Hello, I'm Bayuro. I'm kinda new here on Xentax. I just want to know if there's possible to extract/rip the models which also includes the textures of the city from Akiba's Trip 2 PC? If there's any please share some download links of the shareware used. The truth is I only need the texture of the city. I'm trying to make a city via mapster32 for Duke Nukem 3D. Reply will be appreciated. T.Y.

the quick bms script works for Unpacking the volume.dat the PC version of Akiba's Trip Undead & Undressed

Unfortunately the Noesis Plugin fmt_pepd.py
(in Akiba's Archive post uploaded by prototypesky) viewtopic.php?p=89927
It doesnt work for the PC version and says
version: 692977664
version not supported: 692977664

I tried an older version of Noesis but I'm sure its referring to the version of the Pepd (phyre)

The textures are also in a .phyre format
Its odd because the models contain the words DAE and DDS, soooo how far off can they be?
acctx_glasses_a_001_ps3.dds.D3D11.phyre
chrmd_f_head_goth_n_001_lod0.dae.D3D11.pepd

What I'd really like to do is change the textures and then repack the volume.dat
(changing 3D models would be a fun bonus but tex mods seem more common)

this is doable, though i got to confess that the whole maps are rather wonky at times, did a mrp script to get the files, the worst one to get is chuo_s, the last meshes do seem to do all sort of wonky shit and the textures for it i still have to find them....

exactly as stated before, the textures are inside phyre texture, those are simple DXT1 textures with a phyre header, using RawTex by adjusting the start offset to A68 or A64 you should be able to extract them easy, the models are a bit more complex, this is my code, might be able to help with some of the struct of the game files...
