Did you use cpk.bms to extract the content of the cpk file?
Or you code something out.. goodjob anyway

because this is my topic asking for the new script..
I'm just curious about the models of that game

and you can extract .wav files (encoded by atrac3) from *.awb and *.acb files.
save this code as dumpriff.py:

Code: Select all

#!/usr/bin/env python2
import sys, os
from cStringIO import StringIO

magic = 'RIFF'

for i in sys.argv[1:]:
    basename, _ = os.path.splitext(i)
    with open(i, 'rb') as input:
        output = StringIO() # null writer
        count = 1
        for chunk in iter(lambda: input.read(4096), ''):
            if magic in chunk:
                index = chunk.index(magic)
                output.write(chunk[:index])
                output = open('%s-%.3d.wav' % (basename, count), 'wb')
                count += 1
                chunk = chunk[index:]
            output.write(chunk)

You could use a Noesis script to just load the textures directly into the texture list, which makes them exportable to any of the supported formats and has no external dependencies.

Code: Select all

from inc_noesis import *
def registerNoesisTypes():
	handle = noesis.register("FTX Texture Bundle", ".ftx")
	noesis.setHandlerTypeCheck(handle, ftxCheckType)
	noesis.setHandlerLoadModel(handle, ftxLoad)
	return 1

class FtxFile:
	def __init__(self, bs):
		self.bs = bs
	def loadImageInfo(self):
		if self.bs.dataSize < 32:
			return 0
		self.texInfos = []
		hdrInfo = noeUnpack("<iiii", self.bs.readBytes(32)[:16])
		if hdrInfo[0] != 0x58455446 or hdrInfo[3] <= 0 or 32+hdrInfo[3]*48+32+4 >= self.bs.dataSize:
			return 0
		for i in range(0, hdrInfo[3]):
			self.texInfos.append( (noeStrFromBytes(self.bs.readBytes(32)), self.bs.readBytes(16)) )
		self.bs.seek(32, NOESEEK_REL)
		return 1
	def loadImages(self, texList = []):
		for texInfo in self.texInfos:
			texHdr = noeUnpack("<iii", self.bs.readBytes(12))
			self.bs.seek(texHdr[2]-12, NOESEEK_REL)
			tex = rapi.loadTexByHandler(self.bs.readBytes(texHdr[1]), ".gim")
			tex.name = texInfo[0]
			texList.append(tex)
		return texList

def ftxCheckType(data):
	ftx = FtxFile(NoeBitStream(data))
	if ftx.loadImageInfo() == 0:
		return 0
	return 1
def ftxLoad(data, mdlList):
	ftx = FtxFile(NoeBitStream(data))
	if ftx.loadImageInfo() == 0:
		return 0
	mdlList.append(NoeModel([], [], [], NoeModelMaterials(ftx.loadImages(), [])))
	return 1

(or whatever, only tested with the uploaded sample, version 3.55 or later required)

I have done everything here with neoesis 3.866 and it always game an error on line 40 and line 26
ftxLoad
mdlList.append(NoeModel([],[],[]
NeoModelMaterials(ftxloadImages(),[])))

I don't know what to do with that any help would be apreciated.. thanks in advance

You're quoting pasta's Python script but talking about Noesis errors...

I haven't tried the Neosis script, so I can't help you there. Have you tried pasta's Python dumpftx script? It works well for me. If you don't have gim2png in the same directory as the Python script, it will dump the .gim files contained in the .ftx.
