Original post: 23 May 2009

This is the where all discussion regarding viewing and extracting models from the PSP game FF Dissidia should be discussed, to keep everything nice and easy to find.
If anyone has anything interesting to share, or some potential data files worth looking at, then please post about them here.

Have a nice day  :-D

EDIT: 29 March 2009

MrAdults single-handedly decoded the entire GMO model format and his tool can view and extract Character and Location models!

It seems to work fine with environmental models and stuff too. There is one bug that I only just noticed, which is that sometimes pure static geometry that is symmetrical will get half of itself culled out. I believe they use a surface flag to indicate those surfaces and re-render them with inverse axis coordinates, to save on vertex space. But, I haven't gotten around to finding that flag yet. The only one of the characters that are affected from what I've been able to tell is Bartz. His cape must be "static" for some reason, maybe it's because there's special code handling to animate the verts or something. But generally, since characters are point-weighted, that optimization can't take place on them.

I think that's everything. Enjoy. :)

This fixes that command line switch, and in models with multiple sub-models, you can push enter in preview mode to cycle through them.

And finally, there is a new release (v1.93) of mesh2rdm up now, here:
http://www.richwhitehouse.com/index.php?content=inc_projects.php&filemirror=mesh2rdmv193.zip

As it turned out, lots of surfaces still weren't showing up, like some clothing bits and chains hanging off of characters and weapons. I think I've cleared up pretty much all of the problems now, except for a messed up texture here and there.

The format specification (as much as is currently known) has been documented here http://www.richwhitehouse.com/index.php?postid=34
Thankyou MrAdults!  :-D


EDIT: 08 April 2009

Ukurere has shared his past experiences working with the GMO model files (the same ones in Dissidia) and working with MrAdults, is Wikifying the complete format here:

 :-D


And some pointers about EXTRACTING MODELS using MrAdults mesh2rdm tool:

I use Start -> Run -> Cmd and do all operations this way.
In cmd simply navigate to the path where you have mesh2rdm. Hope that helps.

Aurenasek already mentioned it, but you can use the Start->Run menu and enter "cmd" (without quotes) to bring up a command prompt. Then cd to your model directory where you have a copy of the gmo and mesh2rdm.exe and run it with the desired parameters. You may have to seek out a DOS command reference if you aren't used to using a command prompt, though. :)

I'm using a .bat file that I edit for every file I want to export, here it is if you want to use it:

mesh2rdm File003761.gmo Kefka.smd -dissskip 1 -texpre Kefka -rotate -90 0 0 -scale 1.0 -smdout

That line will export you god form kefka ;P

Neo has all the charactes textures, i guess thats a start..
 
Well, actually, a fried of mine (Who, coincidentally, knows Qhimm himself) is pretty talented at all this extracting and exporting stuff.
If you want, I can ask him to Extract the models for us, and get all the textures. the models, obviously, wont be viewable unless a viewer is available though.

Some texture samples:
cloud-3.png
sephiroth.png
Weapons.png
 
I wonder if the models are also stored in native PSP GPU vertex list format. If they are, figuring them out could be a pretty fast process, with the info koral and I have uncovered on the Crisis Core models.
 
There are actually a few textures I had in mind when I suggested this to koral...(via PM)

I particularly like the Ultima weapon model, Kuja, maybe Squall's SeeD uniform...

I can't remember all of them... but mainly those.
 
Well, i guess i'll have a chat with carey then, see if he can get some models for you guys to have a look at  :wink:
 
If anyone is interested in trying to make a viewer I could send a few Dissidia models, since like I've stated before in crisis core topic, I have no idea of coding :P
 
No promises for the immedate future, as I'm still recovering from my Silent Hill format binge, but sure. Feel free to send them on over.
 
Let me pack them up then and upload, I'll send you a PM with link as soon as it's done uploading.

PS. Want all model files or just a few random ones? All of them are around 240 megs unpacked. (Which means they most likely contain texture data)

The more the merrier. :) But if you have trouble uploading that much data, feel free to just put up as many as you like.
 
Actually I was afraid you might not want too many :P So I guess we both share the same opinion on this - GET'EM ALL.
I'll post link here then as soon as it's done uploading, my network is a bit overloaded at the moment so it will take around 30 mins or so.

Yes, I only need a few specifically, but the more we can get the better.
 
I guess i'll take a look at 'em too. my limited knowledge of everything might come in handy xD
EDIT: Immediately i can see that models start with bone labels...
Then model segment labels? I can see stuff like "p_one100" and "p_one100_wep0" I'm guessing This means i'm in the model for an FF1 character, considering I know cloud's model is called "p_sev100"...

EDIT2: yeah, models have "P_xxxyyy" "P_xxxyyy_wep0" and "P_xxxyyy_wep1" labels. now i've never even played dissidia, but from what i understand, each version of a character has a player model, and 2 weapons (that limit break thing)

EDIT3: then it does something like 2 bytes being "XX 10" and then 2 bytes being "04 00", and this repeats for a while. "XX" seems to be rising every time it comes round, but not in any order O.o

I'm probably just pointing out the obvious here, but i wanna know if anyone can make sense of this.

EDIT4: after this, theres loads of data, and loads of them have this "approximately 00 00 80 3F" thing going on. now after THAT, the bone labels start up again. and after THEM, body parts are labeled ("hair", "cheek" stuff like that)

I did hex through them and I can confirm they contain mesh, skeletal and texture data. The lines starting with GimConv are probably texture headers seeing as default texture format used in dissidia is .gim.

That's all that I can tell since coding is not my thing.

near the bottom I noticed a lot of instances of "f_curve" going on... I'm not sure what it is, but it sounds like either an animation queue or some type of solid modeling function (as opposed to polygonal) which seems to make no sense...

It could be a stored method that is called when the player slashes a wall and the slash damage sprite needs to be bent to fit the shape of the wall... no real plausible ideas though...

actually, Each Model segment has 2 textures, neither of which are .gim
Texture files are stored uncompressed as both TGA and TM2
...i think, anyway.
 
Now if the CrisesCore debug-menu wasn't distracting enough...  :lol:

Thankyou for uploading the files Aurenasek116, I will have a look at them sometime.
Just cannot resist the temptation  :-D


PS: I edited the first post now to make it a little friendlier.
 
I won't say I don't have my own interest in that, so no problem there. I crave so much to get Kefka and shove him into JK3 :P
