Way models NPS (S.T.A.L.K.E.R.: Shadow of Chernobyl)

First you need a program StalkerUE (on the website). Unpack the file with this prog and then UEgamedata-meshes-actors and then I remember, it seems there will be folders with specific models, I hope the name will understand. (UEgamedata will be in the root of game)

If you need to know what model as referred to in the resources, use OGF Viewer.
