[PC] What files defines which PACs a specific Arena uses?

[LordJustice17]

I'm trying to figure out which file tells the game to use a specific PAC for a specific arena. For example, there are only a handful of rope textures. What tells the Raw arena to use PAC 01 and NXT to use PAC 03?

 

I'm hoping that if we could figure this out we could create new PACs (ex: a third turnbuckle PAC, or an seventh rope PAC) and then associate those unique PACs with specific arenas, allowing for more variation in mods.

 

I'm assuming that something would need to be HEX edited. I have very little experience with HEX, but I'd be willing to play around with it a bit, but I don't really know where or in what files to even start looking.

 

Any suggestions?

 

Thanks.

Figuring this out could also be useful for swapping arenas.
