Titanfall 2/Apex Legends

[analblaze]

If anyone hasn't already noticed, the current version of Cra0's VPK tool can't extract a lot of changed files from Apex Legends, and repacked VPKs don't seem to want to work at all right now. There seem to still be some people on twitter opening the stuff that it can't extract though, is there another tool floating around out there or are they just working it out themselves?

I'm trying to form some sort of discipline and get back into this stuff.

Last I recall titanfall2 .rpak was encrypted or packed with a unique compression method.
I'll purchase the game this weekend and have a look.

Perfect news to see.

You can use the following BMS commands to unpack the starpak archives:

Code: Select all

idstring "SRPk" # starpak
goto -8 0 SEEK_END
savepos entryOffset
get entryCount longlong
set entrySize longlong entryCount
math entrySize * 0x10
math entryOffset - entrySize
log MEMORY_FILE entryOffset entrySize
get Path basename
for i = 0 < entryCount
	get Offset longlong MEMORY_FILE
	get Size longlong MEMORY_FILE
	goto Offset
	get Magic longlong
	set Flag longlong Size
	math Flag & 0x0FFF
	if Magic == 0x1800000007
		set Ext string ".msh"
	elif Flag == 0
		set Ext string ".tex"
	else
		set Ext string ".dat"
	endif
	set Name string ""
	string Name p "%s/%08d%s" Path i Ext
	log Name Offset Size
next i

The only problem is files are output without names so there's a simple detection for the extesions.
The mesh format this game use has some optimizations on the vertex data so there're extra work to do to convert them to common format. Some simple mesh is easy to extract though.

NICE! Any progress/chance we can get a BMS script to unpack the .MSTR archives?

What program do you use for opening .msh files?

It's hex2obj that I used to load one of the meshes. But thing is getting more complicated than I expected. Might take a little while to figure out the relation between the vertex IDs and the data.

How would you read the tex files? Is it a dxt format or sth else?

The textures seem to be DXT for the most part

But how did you open them?

The latest progress:


All LODs:

Legion has been released for Apex by DTZxPorter & id-daemon: https://wiki.modme.co/wiki/apps/Legion.html

Models + textures and eventually animations.

Fully rigged + materials in SEModel, OBJ, SMD, XNALara Text, XNALara Binary.

So ive unpacked the starpack files and as asked above all the files are .tex or .msh. How does the Autodesk + the plugins open these files? Usually pretty good with this stuff but im stumped

This is completely useless, follow the instructions on usage of Legion from the link, it uses the rpaks to extract all the assets. The starpaks are merely a bank of data which is used by the rpaks.

Here is a msh to FBX convertor if it's needed. All meshes of all LODs are preserved and grouped like this in a scene:



Tested on msh files from pc_all(01).starpak only.

But is it possible to apply the textures to the models yet? And if so how?
