Trying to make mods for Stalker 2 has been a nightmare, can someone knowledgeable help a fella out?

I have hundreds of hours (maybe thousands atp) making mods for Bethesda games so Im not a total newbie when it comes this type of thing. But I keep hitting brick walls over and over.
Ive spent basically 2 days in a row wasting all of my free time and Ive made no real progress, besides getting a feel for Fmodel and learning the lingo.

Any advice or if theres an in depth guide would be greatly appreciated, thanks.
