Hey!

I got the game files for the Apple Arcade's video game LEGO STAR WARS CASTAWAYS (Gameloft game). I extracted the files - find an extract of the files below -, and I woud like to get 3D models or textures out of the files. But I only see .tx and .bdae files that I can't open in 3D software.

Sorry I'm not very good at extracting files for now, can someone help me out??? I don't know what to do...
I read about Neomis or QuickBMS or Hex2obj but I can't figure out what to do

Thx!!

Both the bdae and tx files have the GCBF header, this format can be decompressed with this script for quickbms:

This is just the first step since I have no knowledge about 3d models and graphics, you can ask separately in the two sections of the forum.

Thx @ aluigi for this first step!!

I succeeded to get dat files from bdae files. I tried several script to convert dat files but for the moment no result. It seems the dat version of the bdae is a BRES file, I looked for some information but no technique explained before worked. There are some broken png pictures in the files that seems to be the textures for 3D models, I converted to dat and it seems these files are KTX files, but I can't open it, even in Mila Texture Compression Tool.

Does anyone know anything about BRES and KTW and how to convert it?


You will find both bdae and png files with their converted version to dat.

Thx a lot

Both KTX and BRES are well known formats and there are many resources both here on zenhax and xentax.
You can search the topics on google in this way (replacing zenhax with xentax for more results):
"ktx" site:zenhax.com
"bres" site:zenhax.com

Hey!! Thx for the quick response

Well I searched as you said on google, but I only found a possible answer for KTX files, with something called 'crunch', and I don't know how to make it work... (https://forum.xentax.com/viewtopic.php?f=18&t=24456)

UPDATE: I suceeded with KTX files thx to PvrTexTools... But for BRES files nothing new...

Were you refering to anything specific about BRES files???

Sorry to be so annoying... thanks aluigi for your time

UPDATE

With Model Researcher I did open the BRRES file, but I can't get the UV right... only vertices and faces work
Does someone know how to find UV?

Thx

Hey! Thx this is perfect!! THANK YOU SO MUCH!

Do you think you could do it on other models (I added some in zip file) so I can see how you've done and I can try myself next time?
Thank you so much!

Hey @mrpood. So far it's a manual work, so quite long to understand and to work with. But if you're interested with some files, you can send me a DM. I know a little about this.

Have a nice day.
