can you help me with this file, I have see many cases but I cant, it is from halo wars big endian can you help me.

there were about 59 people killed in Vegas yesterday so you'll excuse me ignoring this request for rifles...

I apologize if I offended you, I chose this file because I think it is simple and a better way to learn and extract the other files by myself.

I have seen the other examples that you have done with big endian files but I can not extract it.

please correct me

start of vertices: 0x2f90 or 0x2fc0
Startaddress of first face index: 0x38c0

Resulting FIs count: 666

I'm stuck here.

Trying to extract some characters from a game, but I cant make sense of the structure at all -So I am just guessing the adresses.

Would this be something Hex2Obj is capable of extracting?
Could someone provide some advise for adresses please?

not big-endian me thinks, and low poly looking

Thank you very much.

I am applying the same logic in this one(beam_rifle) but I do not get it.
What am I doing wrong?

0x3A00------588
10----------- 99<--- I do not understand this one.
0x31C0------208

please ace xd.

it's not a matter of its capability, it's a matter of your creativity.

Trying out a point cloud, too tired to care fore face indicies:

- LOL

- My creativity did indeed get some new energy now that you showed that extracting from this file format actually could be done.

Great news! - I will keep tinkering with it. - Thanks for a great new start.

you were very close, just had the wrong FVF size, it should be 24 in this sample

In my last posted file and the one in this post - I get what seems like a good point cloud with verts correctly placed.

- What I don't understand is how the point cloud could be good, but the faces are all jumbled up?
The one in this post I have not yet located the UVs, but I am pretty sure I got the FI and verts start adr right so why this result:

wrong start of vertices, wrong FVF size, quads, combined face indices (for vertices/uvs), there's some possible reasons...
Sometimes it's a riddle to be solved.

(Seems it's time to implement a "shifting vertices start" but I'm too busy with a myriad of other things.)

Allright, I know for the car model that I have the wrong start adr of the vertices and I can rule out the other things you mentioned:D
File is sequential, no quads (would be rare for game models I think), UVs and vers are not combined..

Got it down now. Only UVs have some unwanted long lines.

Great!

yep, have a look at testUVs.obj - that's strange...
[...]

btw: it's 'v' instead of 'vt' because it was the simplest way for me to get the uvs displayed (as faked vertices)
