Tom Clancy's Rainbow Six Siege (scimitar / .forge)

Post by Vingeveu »

Hello !

I'm trying to get some graphic files from Rainbow Six Siege but I get stuck.
I used scimitar.bms (viewtopic.php?p=21465#p21465) to unpack forge files that seems to works.
And then I don't know what to do, I tried scimitar_compressed.bms (viewtopic.php?p=33967#p33967) but doesn't seem helpfull in this case.

My knowledge is limited here :( .

I've uploaded some forge file from the game here if you need some samples :

https://expirebox.com/download/aee8b8d6 ... 83838.html
https://expirebox.com/download/99dd5ae6 ... 815a6.html
https://expirebox.com/download/208e5d9d ... 3e0e9.html
https://expirebox.com/download/fb6b2c26 ... 1b769.html
https://expirebox.com/download/ac3e6d50 ... 92a2f.html

Thanks in advance for your help

They changed the file format, so old bms no longer applies. I reversed the new one, so I can extract the contents. But I can't reverse the mesh data and need some help with it. I can provide either sample files or even an entire python script that unpacks .forge files if needed.

Soooo, I kinda got some progress. Here is some of the extracted data https://www.dropbox.com/sh/b2cuse4hp90ym0g/AADXaqKfyrCY9joUtsnlqTfja?dl=0 It includes a bunch of models (some are operators, their heads, weapons etc) in game's native format plus a README of currently known data plus some logs. But I need help with the packed vertex data (marked as Qc and Dc in the README). If anyone can help me crack how it's packed, that would be great.

Is there a possibility to find/extract filenames in forge?
