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

, 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".
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
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
...
Well uv is always a pain for me

, any advice shakotay2?
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.

)
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.):

Oh :'( , I though I was correct, because it looked like this
Thanks Shakotay, I will check the model again and again

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

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

, 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...

I tried with this one, and got the mesh with the uv

, Thank yoou!
