Extract the beautiful scenery and plants of archery heroes, hoping to get help ^-^


The scenery of the archery hero game is particularly beautiful, especially the natural mountains, water, and plants. I want to extract it and try the effect in the 3D software.
Hope to get help, thanks

For sure the data is xored with the string "3dengine", I mean the data and not the archive so it's useless to use "xor" on it because it's not aligned.
I will post if I will have updates.

Are you saying the string "3dengine"?

Excuse me, is there a way to extract this with bms script? @-@

So this is the script:
http://aluigi.org/bms/archery_hero.bms

But the filenames aren't applied to the output files because I still have to figure the 64bit hash algo (probably I will not do it so don't expect updates)

Is 64bit hash algo required for perfect decompression?
It feels difficult

HI Aluigi
Maybe the file was uploaded wrong before,
I re-uploaded 4 files which should be model and texture

file format: .eta .mdo .llo
Extracted 3 formats, suspected to be model files
I don't quite understand these two formats. Is there a way to open them?
Or can it be converted to obj or FBX?

????:

Probably their real extensions are:
.mesh
.material
.col

Because they are the extensions used in the original filenames.

Indeed, I also see that the extracted file names are these 3 various
Is there any solution to this?

I used 3DMAX and some other 3D viewers. Even if I changed the name to .mesh, I couldn't open it? @-@

Thank you Aluigi for your help, I will wait for updates ^-^

There will be no updates since I don't know the algorithm of the filename hash.
Files are perfectly extracted using sequential names.

How to extract using sequential names?
Can you tell me the process?
Aluigi,help me !!

Eh? Didn't you try my script?!?

HI~Aluigi
I did try many times. Although the file name is correct during the extraction process, the resulting file names are these three types, .eta .mdo .llo, which are not recognized

How can the file name be correct?

The following is the process diagram of my operation script
