Help with UVs

[Ginsor]

Hi there,

anyone has an idea how the structure for UVs could be for the attached file?

The UVs begin at 0x6E78.

Any help appreciated!

Thanks

this looks like uvs; not sure how to unscramble them atm:

messer_uvs.jpg

(well - done; had to subtract 1.0 from every uv value > 0.5)

Thank you! Im very impressed.
However, i can not rebuild das, with your tool. Can you tell me, which i settings exactly i have to chose to get that result? i already get corrupt data for "go2".

Also: How did you find out to subtract 1.0 for every UV value > 0.5?

Thanks!

with hex2obj you get the left part of the image in my previous post when pressing the 'uvs' button.

(I temporary inserted the (if (uvpos>0.5) condition) into the code to get the right part of the image.)

it's one of those tricks you learn after having analyzed hundreds of 3D formats.

Oh i see, so I cant rebuild it! Then I need to find a way to build an .obj for that somehow. Any idea how I could achieve that?

Haha, I get that. Thank you, it is a very useful info.
Also, why is your count 753? Shouldnt it be 1761?

In hex2obj switch to ShortAll, then File / SaveAs mesh
Load the created obj file into a calculation app (Excel or so), blank as a separator , for the vt lines you should get three columns for "vt", tx and ty. Select the tx column apply a formulae which expresses the above conditon (same for ty column), save the changed table and you're done (more or less).

Maybe; didn't check that. I care for the first submesh only in most cases.

Yea, I did that even before reading your post. Came to my mind as well haha, thanks! When i imported it to blender it still looked messed up tho! I will give it another try tonight when i get home, but in my first attemp the UV map in blender looked not right.

Wait, you can see that there are submeshes inside? Sorry, Im a little lost now. For me it all looks like just one big mesh with 1761 counts for vertics and UVs.
Thanks for all your help tho! I appreciate it a lot.
