I want to extract a 3D model from afile, but I don't understand the structure of the file, which is a hair model. Attached is the model file and the map and an xml file.
I'd really appreciate it if you could help me with this detail.

This is really cool, can you tell me how you got it?Thanks

I got this with Model Researcher, there is other block at 0x1E133 but I don't know what that is..

Oh and there is other small mesh at 0x134020

Thank you roocker666, you gave me an idea for my follow-up research.

11 00 00 00 14 00 00 00 8F 07 00 00 73 27 00 00 64 D9 01 00 01 00 00 00 02 00 00 00 00 00 00 00

73 27 = 10099 = count

11 00 00 00 14 00 00 00

Searching for 11 00 00 00 14 00 00 00, I found there are 13 in total.

it have 32 bytes.

Ok!, I guess that is a clue to find the header of some blocks but it seems like for faces is: 10 00 00 00 14 00 00 00 because there are only two.

I feel like you are right.

using hex2obj

(The counts need some adjusting, I guess.)

And there's dozens of superfluous faces inside.

Interestingly it looks much better when you use the face indices startaddress from roocker666, 0xc5c6b.

Games using H3D engine

Now, I am able to extract v, vt, and f from the file. May I ask what else I need to extract? There are 4 unknown locations on top of which data is stored, and I am not sure what the purpose of these data is.

01 00 00 00 02 00 00 00 -> v

02 00 00 00 02 00 00 00 -> ?

00 20 00 00 03 00 00 00 -> ?

10 00 00 00 01 00 00 00 -> vt

00 40 00 00 03 00 00 00 -> ?

00 80 00 00 03 00 00 00 -> ?

I don't understand modeling, I don't understand what the other data blocks represent, and how I can verify their authenticity. If you could provide me with assistance, I would be extremely grateful.
