How would I find individual item names / codes in Read Dead Redemption 2

[sprdc]

I want to try and create a BDSM mod for RDR2, as there are all the assets I need in game already. However, I lack the knowledge to pluck these individual assets out - for example rope textures/ animations for hogtying. There is a gag texture already in game however I don't know how to find it... so not much luck rn. If anyone can guide me in the right direction, that'd be really appreciated.. I already have OpenIV... but I have no idea what I'm looking for!
