I start to love this monologue. hehe. It helps me think. Hope it helps someone else too. (: I discovered the best way to understand what is what in some 3d model file. It's god damn simple. I locate 3d model file in memory (using IDA) just after it's already decompressed. Then i open memory with hex...

And hello again. :) I was thinking about the way to understand the format of meshes. I tryed to discover it using just a hex editor. It didn't help much. Then i thought about ida again. When the mesh file is loaded into memory and decompressed i can easily find it in the memory dump and set some bre...

Thanks for tutorial. :keke: As i understand, this method can be used for exploring file format. Right? :? I can check if some portion of data represents vertexes, but how about triangles, bones and normals? Then we'd be good. Also. 19) save the file as a csv file open the file in hxd do a replace an...

I think this is not the right place to post your stupid spam. I'm sure now that spammers are the most retarded "people" in the internets. But yeah, they have enough brains to use bots to post spam. Rrrrawr. I can't just pass-by when i see something stupid like this. I request raid against ...

Thanks, but seems like i'm not good enough even to log in (: . Shame on me... Well "understand Japanese" in my case means "i'm still noob and need dictonary all the time". Feel myself like a dirty liar :( Anyway, i don't believe there is no information about it in english. I've s...

Ouch... Looks like i'm busted
Ahh, whatever Not so many people will go so far to put their hands on these models.

Anyway, thanks again ^_^

Ok... I've found Milk 3D. Soft has SDK, so it's possible to write your own plugin for it. Looks like it's possible. BUT. The program is shareware and i'm poor pakistan programmer with 7 children (yes, i'm not serious) so there is no way for me to purchuase it. Is there any immortal tool (that lives ...

Where to start, what to read, what soft is available? I'm starving for information!

Fix: I renamed topic, because "Reverse engeneering 3d models" is a process of digitizing a real model.

GOD DAMN SPAM. Moder! Are you sleeping or what???

Solved
2 weeks = now i know how to reverse games. Curious. Did'n think it's so easy.
If anyone still interested, compression algorithm posted here:

Topic can be closed i think

Developers are smartasses nowadays, they don't use popular algorithms to compress their data. I just reversed my first gamepack (yup, i'm still noob) and you know what? Compression algorithm is unique for the game i reversed. So i think you just have to get your game and reverse its exe file. It's p...

Working! I don't believe i just did it. ^_^
So much thank you for clean C.
Now i only need to understand the format of meshes. Hope it will be easier.

As i just discovered the said function only reads strings like 'data/Textures/blabla.texpack' letter-by-letter and converts them to lowercase. I'm LOL x) Nevermind. i've finally found the right function. Here it is, in all its glory: (its C) int __cdecl Uncompress__No_Really(int START, int END) { in...

Thanks for reply.) This game is multiplatform - xbox is main i guess. (because function for reading files refers to XBoxFileHAL.cpp) I tried XMemDecompress, didn't work. (I still hope to get this game easyly....) :cry: Maybe you'll take a quick look at the attached file? Some strings are readable, s...

Hello... I've spent about a week with IDA pro, and... YES, i've finally discovered the possible uncompression function used in "my" game. Pseudocode by hexrays ( :ninja: ) void __cdecl unCompress_function(int a1) { int *v1; // esi@1 char v2; // al@2 v1 = (int *)a1; if ( *(_BYTE *)a1 ) { do...
