Dragons rise of berk Ludia

[tontonGrim]

Hello,

I would like to extract textures, 3d models and animations from the game Dragons rise of berk on mobile from Ludia (mobile android version)

I think I succed to extract the files with Quickbms (ok for pvr and wav files), but I get some .dat files, which I cannot read with Neosis ...

Could someone help me on this?

Thank you

ps: i joined a this mail a example of folder with .dat files

Hello, Acewell


Thank you for your comeback.

is this a model contained in the file?

If so what did you use as a tool to do this?

can we recover the meshes and the animation (I would like to import them into unity after)

i tried to use neosis to extract some things
but without success

You are a joker because you don't tell me anything! ...

i tried to go here...:

But is too complicated for me ...

yes this was the model in the 000004be.dat sample

If so what did you use as a tool to do this?

i used Hex2obj and Hxd and windows calculator

can we recover the meshes and the animation

you can get anything you want if you know what to look for in hex editor.

You are a joker because you don't tell me anything!

the offsets and counts in the image tells you everything.

Hello Acewel

Thank you,

i repeated your parameters and i found the mesh for the 000004be...

but how find the otht parameters for others files ? (ex for the 00000497.dat etc.... he have more 40000 files !!!! ... (((( )

i refind this topic:
viewtopic.php?t=20733

But I don't understand how Hex2Obj works ....(and i m french.... )

is there any other way than using hex2obj?

Hello,

I come back !

I used Models Researcher 2.7 with the file 00000497.dat (see attach file).

I found the vertices (see attach file), but i cant find the faces..... can you help me ?

files.7z

Best regards

[Acewell]

face indices start at 0x13128
looks like there is 8016 of them.

[tontonGrim]

Thank you Acewell,

i tried it but i have error message "mismatch of faces and vertices"...
(see the picture)

Where is the problem ? format of face ? padding ? i tried several parameters but without success

i don't understand why ...

ps : i put 8016 in count parameters but i have a other message "can not read data" the system is out of limit, for the moment i put 10 in the count parameters (see the picture)

thank you for your help

[Acewell]

i guess you need to change the Type for faces to "short".

Hello Acewell,

thank you very much for your help !

I tried to choose "short" in the type of face, but it's not sufficient...

But i don't understand why, if i use Hex2Obj i can create a good obj and texture (with your informations)

but if i want try to do the same thing with 3D models researcher....

I can't do.... and i obtained this.....

I tried to modifing padding, padd inter etc.... but nothing...

Thank you

ps: In your previous picture, at what corresponding the FVFSive parameter ?

In your previous picture, at what corresponding the FVFSive parameter ?

FVFsize is the stride in bytes for vertex information. i don't use
3dmodel researcher so i can't help you there, maybe ask the developer.
