Ripping for rookies? Or sites to check?

Plain and simple, I want to get started ripping assets, specifically from Rainbow 6: Siege. I’m primarily interested in the weapons and armor, and from what I’ve been able to find via Google the stuff I want hasn’t been uploaded anywhere else.

So, is anyone willing to help a complete FNG learn how to do this? Alternatively, is there a list of sites I could check, on the off chance Google missed something?

I think there is a Rainbow Six Siege thread somewhere on the site, however I don’t know when it has been updated.

Also check for 3D models. You might find some stuff you need.

Edit: R6S thread
