How to make a npcs from MI to gmod?

Hello. I want to make a HL2 Leak Pack for Garrysmod, but i don’t know how to port npcs from Missing Info mod to garrysmod.

I dont think you know how this works. You would have to recreate the npc’s with lua code. There used to be this thing called gm_mount2 but i do not think it works anymore, and you cant use it for an addon pack anyways. so i suggest you start learning some lua
