How about everyone posts his complete know-how about the .LZS model files to decrypt it evt. 100%? Are you afraid that you have to credit other people in your application? Shame on you...

I had not looked at models with textures yet (UV-Coords in Color-data?)

ENEMY000.LZS - Yellow Pyramid
More detailed data follows tomorrow but first:
Now it's YOUR turn.

Excuse my ignorance, but aren't .LZS files supposed to be compressed?
and if so how can I uncompress them? (lzs.exe from Ficedula's site seems to constantly crash on either XP or Win98)
Thank you in advance

Welcome to the Forums Anakin. We will be watching your career with great interest...

Please don't bring back dead topics like this if you don't have something to add to the discussion. It's in the rules.

Yes .lzs files are compressed. If ficedula's app isn't working for you (makes sense--it's designed for files from the PC version), the only other one I know of is a tool written by M4v3R. I can't find a working link, though, so you'll just have to hope he posts one (no whining/begging, please. I don't have it.)

Quote from: ShinRa Inc

the highly detailed Cloud and half-Jessie models are never used in the game.

Quote from: Contra

that model was used in the scene where you and Jessie are standing in front of the monitor, and she explains the Midgar rail system to you. I've seen it in the PC version, using I believe Ifalna. There is one of Cloud in the same scale.

After a quick Techdoc consultation, it looks like Contra is correct. Here's proof:
The train monitor location is rootmap.
rootmap loads the following two 3D models:
clgd.hrc -high res. Cloud
cmde.hrc -high res. Jessy upper torso

Hmmm well the thread isn't dead however it's just not been active because I ran into trouble with getting OpenGL to apply textures to surfaces, I don't know what I am doing wrong either.

As for compression
All LZS files are compressed, in fact almost all files are compressed in FF7, I suppose if they hadn't done that they couldn't fit the entire game on 3 disks (4 like the successors). FF7 had a lot of cool ideas in it, however I think 1/3 of them never saw completion (such as the Shinra dolls).

Suggestion don't quote a huge section of text next time

If you have questions regarding the Battle models for the playstation version ask away

Well in fact I'm also interested in the simpler -deformed- character models that are used throughout the game (always refering to the PSX version).
I would like to be able to export the coordinates of the shapes that make up these characters as well so I could reconstruct them in AutoCad or 3DMax.
Only I don't know where to start from, where to look...

Dont know about PSX files ... if you are interested in PC files this is possible.

Yes, I've seen it done in another thread (PC version).
You know there is this program FF7vm001 http://www.cute.or.jp/~makuchan/pce/ff7v.html which can view the 3D models of PSX version, but it has no option for extracting them.
Hence it IS possible to manipulate the PSX files on a PC, the problem is how is it done?

Naitguolf · « **Reply #82 on:** 2004-04-09 16:17:09 »

why using PSX files when PC files are more easy to use?

Anakin · « **Reply #83 on:** 2004-04-09 16:32:18 »

Are you sure the models are identical?

Reno · « **Reply #86 on:** 2004-05-01 14:13:32 »

Hmmm, I seem to be getting a small bug with this program, whenever I convert it to 3DSmax, the character's are missing facial features/textures and some of the polygons are off. Is there a fix for this?

Rubicant · « **Reply #87 on:** 2004-05-01 19:13:06 »

Well, the models come with .tex files, which contain all of the eyes and mouths that would appear on the models. I haven't screwed with 3DSMax in a long time, especially with ff7 models, but as far as I know you'll have to paste the textures onto the models manually.

Mofokubik · « **Reply #88 on:** 2004-05-02 04:07:20 »

When you load it in 3DSmax I doubt it loads the materials with it. You will have to apply them yourself I guess...

Reno · « **Reply #89 on:** 2004-05-02 09:18:42 »

Hmm, that still doesn't explain that polygons being misaligned. Perhaps there is a fix for Biturn that I missed...

Cyberman · « **Reply #90 on:** 2004-06-18 17:36:42 »

Alright Kislinskiy
why Icouldn't make heads or tales of the 'unknown' part of section 0 of the model files. Please so DOH loadly 3 times .. it will make me feel less stupid

here is a BETTER look at the structure of the begining of that section

Code: [Select]


typedef struct
{
   UINT16 Parent; // parent bone
   INT16 BoneLength;// length of this bone (not completely understood yet)
   UINT32 Offset;  // Offset to data that belongs to this bone
} bone_data;

UINT32 BONE_COUNT;
bone_data ROOT_BONE; // There is always a ROOT bone even if there is no model data!
bone_data bones[BONE_COUNT];

That's it.. kindly beat your head against the wall and laugh like a madman it's so simple ARGH. You have a ROOT BONE, I was always ignoring that thinking it was just empty data, which it is. So basically at 0x0000 you have the count of bones then the Root bone then the actual bone information. You may now sigh and let out a light scream.

Essentially the root bone is all zeros and that was what was confusing me. Any bone that does NOT have an offset is a JOINT! (IE if the Offset value is 00000000) and has no visable data. That's it.. I know, too simple

Cyb

Kislinskiy · « **Reply #91 on:** 2004-06-24 19:05:48 »

That's also new to me.

The last time I looked at this file format was in January. I know about the Parent-UInt16, the root bone and the joints but I didn't know that the negative values are the bone length.

[loud]DOH!! DOH!! DOH!![/loud]

Cyberman · « **Reply #92 on:** 2004-06-25 07:34:45 »

So basically it's kind of empty data bone lengths and offsets to bones and joint lengths. NO position information but the lengths are there and there jointedness is 'obvious'

I'll post a 'structured' decoding of Yuffie sometime.

Now.. if someone would kindly put up the other data information used to position the parts in the PC version I bet one could figure out the thing on the PSX quickly (mumble).

Maybe its like in PC version, in skeleton file are only lengths and parents of the bone, and rotations of the bones are in different file.

Well they aren't seperate files however, they are seperate sections.

For example Section 1 of the PSX file has the following information
bone information
visable structures.

the bone information is a binary equivalent to the PC's HRC data
the visable structures are binary versions of the PC's RSD formation

The bone information has offset references to the visable structures for regular bones and a NULL offset for Joints.

SO if you have the file format for the bone rotation information for the PC let me know! Because then I can piece one of these things together from that on the PSX which is all compiled.

mirex · « **Reply #95 on:** 2004-06-26 08:54:08 »

Yup I have to have it somewhere, i've coded those long time ago into biturn
-- going to search for sourcecodes --
So i bustled some raw description of PC FF7 anim file .. here it is:
http://mirex.mypage.sk/FILES/ff7_a.txt

Cyberman · « **Reply #96 on:** 2004-06-27 01:27:08 »

Looking at that indicates to me that it's some intermediate format they created and nothing like the HRC or RSD files I guess they started making there own proprietary first hmms.

If it's not in ASCII it probably isn't the base format (sigh). I wonder how many text files are in the PC version.
