look for point clouds, then look for face indices, it's DWORD here:

I'm very thankful to you.
And how did you find the point clouds?
And one more question, does this file have a submesh? Since there are several "alphabetic tables" in it and three identical hex codes: 08 B6 FD CF 05 2E 77 34 CD E9 20 B7 F8 CB 62 F9
Sorry for my English.

Hi again!
Im here for models of MotoGP 17 the game
The models of previous game of milestone (MotoGP16 and Ride2) are perfectly extracted but I have problems with the new files of the new game..
I can do some parts of the extraction model but when I push the buttons "mesh" and "uv's" something are wrong.. I cant understand
Can you help me? here is the file

Thanks!

it's a combination of trial and error and experience

yes; I usually search for one submesh only and leave the rest of the work to the customers

Oh thanks!! My problem was start addr of vertices
the rest of values was the same haha
You help me a lot, thanks man!

Hi Shakotay2,
Can you tell me how you draw uv in your program?
I connected every 2d coordinates to create lines but it didn't work.
This is my code
Code: Select all
from Tkinter import *
import scanf
master = Tk()
w = Canvas(master, width=200, height=100)
w.pack()
uv = []
input = open("test_uv.txt")
scale = 100.0
for line in input:
x, y = scanf.sscanf(line, "%f %f\n")
uv.append(x*scale)
uv.append(y*scale)
input.close()
w.create_line(uv) # x1, y1, x2, y2, ... , xn, yn
mainloop()
Here is the right UV:
Attached right there is an example uv.

Hi,
I don't draw lines. hex2obj just sends the test_uv.obj to the mesh_viewer.exe which displays the uv map.
uv data in test_uv.obj as faked vertices:
v tu1 tv1 0
v tu2 tv2 0
v tu3 tv3 0
f 1 2 3
The important thing is the face indices which you don't take care of when just connecting one uv point to the other.

Can you guys help me with this file?
Link:

I still can't find out where is the uv address

First of all: I wouldn't like to have automatic weapons in this helper thread as "samples". Please open another thread for such, thx.
Secondly I'd care for a decent point cloud before searching for the uv (vertices start address 0x165 is wrong).
Face indices are DWORDs (DW).
H2O file:
0x1BBC1 9918
Vb1
28 99
0x9309 2713
140000
0x9301 28
In this sample the vertices or following the uv data. Since you can't use a negative uv pos so far you have to circumvent this by defining an uv block with a startadress of 0x9301 and the same FVF size, 28 (a little bit tricky but works).

sorry, one more question
how to export to obj with uv? I've imported to ms3d and there is no uv, although I tried to import "testUV.obj" as import obj(UV)

use File/SaveAs mesh to export to obj with uvs

Hi
Can you help me with this model.
I have found verts offset and normals offset but I can't find face indices.
verts off = 0x80 vertsCount = 594
By the way where is the exe with fake button?

Hi, point cloud with 1191 vertices is o.k. but faked indices give a rather ugly result.

It's not a "fake button"
,
it's a button for autogenerated ("faked") face indices:
viewtopic.php?f=29&t=10894&p=119417&hil ... ed#p119417
(well, I didn't name it "auto" since that would pretend to calculate proper face indices.
But "Fake" does not, it just creates f 1 2 3, f 4 5 6, and so on (or strips) and in most cases it looks bad, because it's "faked" face indices.)
edit: formulae for triangle strips:

What algorithm is used for autogenerating faces?
This is from ps2 game and I have read ps2 games calculate faces somehow.
Can you give me hint how to do that?
This model's faceCount is 470 but I don't know how it is calculated.
