Hello, everybody

I need help for Converting the models from Bloody Roar 3. The format is different from BR4, it doesn't look like a Renderware DFF format as in BR4 (I guess Eighting started using Renderware Engine from BR: Primal Fury afterwards.) Much looks like a standard "PS2 tri-stripes" model file but without chunks separator.

I tried using hex2obj, but I'm kinda lost at searching the UV/Vertices address

Here's the sample if needed:

could you tell more about it? I've no time to check that out.

Talking about this data?

well: these seem to be too regular (even if I'd handled them as tri strips, I guess) as to be face indices:

Did the face indices address located at the end of the file? because that's what I'm thought when look some data that resembling scrambled alphabets at 0x628B0

ah, yeah, must have overlooked them. But they aren't too many and biggest face index seems to be 128 (0x7F+1).

Another idea would be to start from 0x5E0B4 but its DWORD DWORD WORD index here. Very strange.

Maybe pick up the smallest TTM you have and analyze its structure completely?
(Will take some time but at the end you'll know more... )

Maybe it doesn't use indices and 3 pairs of verts each form a triangle.

yeah, but which pairs? From the first 100 vertices there's two simple 15 points mesh parts
which you could imagine how the faces would have to be build - then look for the belonging indices.

But I don't have the time for such.

edit: I've tried to give 0001.TTM some structure:
(pattern 1A cnt 00 01) found 339 lines with no senseful face indices.
The vertex count is 383 (0x17F)

Hello

using FurryFan's BMS script to unpack the "IMAGE00.DAT" I was able to look at the "TTM" files, which I assumed are models.
But there are other file types with the same base name, which makes me believe model components may be spread across other files.
SEQ: File Record?
TTM: Geometry?
TI: Textures?
MOT: Animation?

So far I have got mesh loading working for some static models like stages, but skinned meshes look pretty bad.
I'm assuming I need the skeleton transforms in under to get the model vertex positions correct.
And also I have not yet seen any texture map coordinates at all in the TTM, I'm starting to think they are in the TI (texture files)?

My Progress on the TTM format:
Block Structure
HEADER
MESH_TABLE
VERTEX_BUFFER
UNK_BLOCK01
UNK_BLOCK02
UNK_BLOCK03

The mesh table gives definitions for each object and contains a count and offset to a stream of draw commands for that object.
Certain draw commands are followed by 3 face positions repeated by a count given from the command.
The format of that would appear to be like <Vertex Colours> <Vertex Index> <Vertex BoneID> <Vertex Weight> ... but not sure?

I encountered two commands 0x11(Static) and 0x26(Skinned).
With 0x11 a series of 6 floats are missing that I assumed were floats, but when added up exceed 1.0 as a weight..

Below are some structures I made:

HEADER {
LONG fileid
LONG unk
LONG mesh_addr
LONG mesh_count
LONG buffer_addr
LONG buffer_count
LONG unk1_addr
LONG unk1_count
LONG unk2_addr
LONG unk2_count

}
DRAW_HEADER {

}

Hi, is there more progress in this model format? o.O
