Hello I was trying to get the model inside this file, I have used the start vertices (1280) and start face indices (7A64) in hex2obj, but still not getting any viable mesh, and still cannot identify nothing about uv :cry: , any help gonna be awesome! thank you for read and your time!

I wouldn't say it's a simple format but after years
I'd say you'll need something that is called a "plan". :D

I.e. starting with a point cloud, for example.

I'll leave you alone with this H2O file which reveals some shape:

0x7A68 2467
Vb1
32 99
0x127F 625
021000
0x0 255

Start address of face indices maybe wrong, uvs not set, and so on. Good luck. :)
(resulting mesh will look better than the shown one because of some last parameter changes)

OH it was! (0x127F) I missed that "6" lol, and about the start address of face indices is (7A64), surprisely I was correct :roll:

0x7A64 2469
UV 32 --- ?
0x127F 2467

Well uv is always a pain for me :( , any advice shakotay2?

Seriously, you were not! (: I don't say that 07A68 is correct but 0x7A64 is simply wrong. Look at the resulting test.obj then:
...
v 1.420595 0.056065 2.946092
v -9223374235878031400.000000 0.000000 -0.000000
...

I have no idea here. After 0x60A0 a "number/weight" table seems to follow, something like this.
(Well, some number is 343, so no bone numbers. :cry: )

Obviously there's enough floats in that table for uvs. Be creative to arrange them - I don't have the time for it.

Hi, I think I found UVs, so it is something like this:
0x127B Vertices count(71 02 00 00)=271 Hex=625 Dec
0x127F Vertices address

For UVs just add 12 to vertAdd

Faces:
0x7A66 Faces count(A2 09 00 00)=92A Hex=2466 Dec
0x7A6A Faces address

The mesh looks weird because there are a lot of extra polygons, so you need to delete those maually(I don't know other way, lol.):

Thanks Shakotay, I will check the model again and again :lol:

Thanks rocker666! gonna take a look at the valuees!!

hahaha there should be some value that is causing it, but is taking the form!! :mrgreen: , Thank you

yeah, cool. (That's FVFsize/UVpos 32 12 in hex2obj, btw)
0x7A6A Faces address
That did the trick with the uvs. I can't believe that 0x7A68 could have such an impact on uvs (making them "unvisible" in hex2obj) edit: hmm, strange, recheckt with 0x7A68 and I should have seem them ->growing older, but not wiser... :eek:

I tried with this one, and got the mesh with the uv :D, Thank yoou!
0x7A64 2469
UV 32 12
