Killer Instinct .kimesh / .kihkx

[TFA]

I'm not extracting for people anymore.

So, chrrox from the Game Archives forum was able to make a pretty awesome unpacker script for the latest Killer Instinct. However, as one might expect, all of the file formats are proprietary. Here's what I've been able to gather so far:

• Almost all files seem to be prefixed with .ki besides the .xml files, which are standardized.
• File endings are mostly self explanatory, with the exception of files with the extension ".48" and ".51"
• In the characters/charactername/ folder, there are textures, materials, meshes, and all relevant data.
• ".kimat" contain the shader parameters, while ".kitex" contains some form of texture.
• As I understand, .kitex aren't simply renamed .dds files, as I noticed an internal path while briefly scrolling through with a hex file. However, due to the file sizes, I'm assuming they have a standard DXT compression scheme. I'm still very amateur, so I may be wrong about both of those.
• Interestingly, some textures are suffixed as _fresnel or _fresnel_variation_2. Might these be cubemaps?
• ".kimesh" presumably contain the mesh data, and I'm assuming that ".kihkx" is some form of Havok skeleton file. It may also contain animations.

So what is in the zip file? -> ok it is black orchid

Did you check if the texture has an atlas header?

Point cloud of kimesh is promising:

You're in luck, kihkx is 100% normal HKX file.

However, AssetCC gives us this:

Code: Select all

Binary Packfile has the wrong endiannes or pointer size. Predicates won't be read.

This is probably because this game uses some crazy version called hk_2014.2.5-r1, while the only 2014 tools available are hk_2014.1.0-r1.

I can probably mess around with it some more but I'm still busy trying to fix 2011 files from SD.

Here is the first sub-mesh (if it helps to understand the format)

[shakotay2]

(if it helps to understand the format)

thx - the problem is to find the start of the next submesh.
If you set the face indices count to 2001 you'll see what I mean.
(1848 seems to be the correct value for the first submesh , without misfitting faces)

Dunno if there's a problem with hex2obj, I calculated the next addresses (just leaving the FI count as it was) and it works (one face missing, so 1854 is correct here):

orchid_2nd3rdSM.jpg

edit: did the same for the 3rd SM but it's a tedious task.
(There are magic tables with 1842 and 1860, which are -6 and +6 off, so I'm a little bit confused.)
That would mean the FI's startaddress of the 2nd SM to be 0x5028 with a count of 1860.

I'd like to dive into this and start participating too. I've got Hex Workshop and some motivation, so where should I start?

Huge thanks to everyone for their work so far. I figure a couple more meshes might be useful for identifying a standard, so I've taken the liberty of uploading one from each game season: https://r.kyaa.sg/wqjscv.zip

[zaramot]

Hey Szkaradek123! I see you made great progress with Killer Instinct, are you going to finish it? I'm thinking to pick this game and try to solve model - import part, though if you're working on it I will pass over, you will do this better than me

[shakotay2]

Hey Szkaradek123! [...] you will do this better than me

better than everyone, I guess...

Dunno if there's a problem with hex2obj

nope, it's just relative face indices, so you can't "merge" two adjacent submeshes with hex2obj

But I'm still having a problem with SM7 (..SM10):

orchid_submeshes.jpg

[zaramot]

Cool, you're missing one array of values for correct vertex-stream offsets. Okay guys, I'm going to finish this one, so please if someone working on it or maybe in a "finish" state for import script/plugin. Write few words here, just don't want to waste some time, if anyone already doing this I don't mind if anyone pick this up, I might switch to DOOM or any other game xD



File Aria.kimesh

[shakotay2]

Cool, you're missing one array of values for correct vertex-stream offsets.

yep - I was in the hope to solve it without that vertex info list but for some unknown reason those nasty developer guys mixed the (address) order like this: 0,1,2,3,4,5, 9,6,7,10,8 so I've surrendered the idea of making a tutorial for it because my C code is very ugly now.

orchid_SM8.jpg

[zaramot]

Yeah, what a nasty developers Though, I've met even more crazy things in 3d formats unfortunately, why they not making things easy xD? We just want models! BTW, I want to ask topic creator for more .kimesh samples, all .kimeshes he provided importing fine with my correct "alpha" script, but I want to try more.

judge.kimesh

[TFA]

I took the liberty of uploading every character-related .kimesh from the game: http://www.filedropper.com/meshpak
If that's too large, I can upload just the character models. The archive I uploaded includes cosmetics and other bits and bobs.
