Hot Wheels World Race NGC Script Help

[reh]

Hello, I hope you are well.
I spent time playing with this script, but I can't seem to get it to work. So the message that appears tells me that the buffer is not correct, but I don't know what to do.

Here is how the model is loaded with Hex2obj:

Here is the script plus some sample files:

Script + rom .zip

Thank you for your help!

Hello,
do a correction of one line only, DWORD FIs here, means 4 instead of 2 bytes:
FBuff = bs.readBytes(FCont*3*4)

btw: "FCont"? In english you'd better choose "FCount" or "FCnt" or "FaceCnt", just as a thought.

[reh]

Thank you very much , now the script loads the templates, I still need to edit it to load the second mesh, the way I did until it loads the second mesh, but stops loading files that have only one mesh.

btw: "FCont"? In english you'd better choose "FCount" or "FCnt" or "FaceCnt", just as a thought.

Thanks for the tip, I will make changes to the script and then post it here.

Can you tell me how did you extract the .bah/bad archive files?

Here I attached the converted file in Wavefront .obj format.

Can you tell me how did you extract the .bah/bad archive files?

I extracted the files with the script found here.

Here is the script for the templates, so far with the files I tested it worked fine.

Now, my question is how to get the textures? In the link where I found the scripts to extract, they say they are dds files, but the best thing I can do when trying to extract with Texturefinder was the following:

If anyone wants to help , I'll post some samples here.

I have finished my Hot Wheels: World Race .rom loader module and I have released the following program as web updates:

- 3D Object Converter v7.034 (Windows)

How to get the 3D Object Converter:
Download the 3D Object Converter from http://3doc.i3dconverter.com and install it or download and use the portable version.
After it just use the Help/Check for updates... function to get the v7.034.

I was trying to add the material name, with this code:

Code: Select all

MaterialNames = (bs.readBytes(16).decode("ASCII").rstrip("....ÿÿÿÿ"))

My intention was to ignore the "....ÿÿÿÿ" that appeared after the name, but I am getting this error:
UnicodeDecodeError: 'ascii' codec can't decode byte 0xff in position 8: ordinal not in range(128)

How should I ignore these characters?

Without showing the hex bytes you're reading no one can tell.
I assume the problem might be the "..." - rstrip() doesn't use them as wildcards, does it?

Would these be:

well, you simply need a function which reads zero-terminated strings, don't you?
Seems you need to create it for yourself - found a base in fmt_Torchlight_mesh.py,
modified:

Code: Select all

def ReadStringZeroT(bs):
	name = b''
	b = bs.readBytes(1)
	while b != b'\x00':
		name+=b
		b = bs.readBytes(1)
	return noeStrFromBytes(name)

use it like so before your for i in range(1): loop

Code: Select all

	bs.seek(0x48)
	print(ReadStringZeroT(bs))

(btw: for some unknown reason while b != 0: doesn't work, why?)

[Acewell]

Code: Select all

MaterialNames = bs.readString()

should suffice.

[reh]

Thank you very much, I will test these tips

Edit: The first code that Shakotay posted until it works, but if the model has more than one material, how would I do it?
I tried to put it in a loop, but it didn't work.

How would I use this code?

Code: Select all

MaterialNames = bs.readString()
