Importing gmod models into hammer?

ive tried this before and failed, it looked like this in hammer:

basically, the basic dimensions were there, just the geometry wasnt. when i try to compile, hl2 crashes.
I made a models folder in the half-life 2 episode two\ep2 directory and put the model folders in there.
all the files were vtx, mdl, phy, and vvd files. i also made a models folder in the materials folder.

does anyone know how i can fix my problem/ how i am supposed to import models?
thanks in advance

I’ve tried before… it failed. I believe it is the vtx file that needs the right directory for the model to show so if the model was compiled to be used in garrysmod/garrysmod/addons I think you would have to make a new folder in your models called garrysmod/garrysmod/addons then place the whole model file in there. Other than that, I wouldn’t know. Maybe the textures are screwed over?

No, just copypasta all the models and materials into your main gmod folder. S’how I got PHX models to work in Hammer.
