Magicka .XNB model files.

[pechenko121]

Can you guys help me in extracting meshes from this .XNB files? Game built on xna framework. I searched for programmes that can open those files but was unsuccessful.
Thanks in advance, i really appreciate it.

Here's some samples.

Did you look at this ?

http://xbox.create.msdn.com/en-US/sample/xnb_format

it contains a parser for the xnb format, maybe use it to write out obj or somthing?

edit: I tried it and it recognized it as a compressed xnb format, probably using some kind of hash from the program itself as the salt, if that is the case, no way you would be able to uncopress that

Oh, that's weird. Thank you.

With these files the method did not work

[shakotay2]

because they are compressed. Search for xnb.bms to decompress them.

Won't help you either because ParseXNB doesn't have a reader for this: 'ColladaAnimation.SkinningDataReader'.

Concerning the mesh as almost always hex2obj is your friend in case you invest some time:
.

Copy the 6 lines below into an empty *.txt file and rename it to whatever.H2O
Load the model into hex2obj then the H2O file, press the 'mesh' button to get the model displayed.

Code: Select all

Thank you very much

[shakotay2]

The mesh format appears to be simple, maybe search for 'default' to find the counts (must be verified with more than one model, though):

This method does not work with the other model of the same game

[shakotay2]

This method does not work with the other model of the same game

Using hex2obj as a "method" works in most cases, 70.8% of them.
A H2O file, indeed, usually works for one model, even worse, for one submesh only!

H2O file for the head:

0x9111 1854
Vb1
52 12
0x1FB3 467
020000
0x0 255
.

(Mesh format seems to be simple but these low poly models don't motivate me to handle them in a Make_obj project.)

so how do i do with the other model

[shakotay2]

Learn how to use hex2obj (press 'tut' button for reading).

Use description here

to get the counts.

(face index count = face count * 3, btw)

[CameronCarson]

xnb-counts.png

when I find this value how can I transform it into a .H2O code

[shakotay2]

It's not "code" it's just "parameters" (values, addresses, counts). With a model loaded enter parameters then press File/Save H2O.
