In this guide, I will attempt to teach YOU how to port full addon models into pac3.
First off we need two tools. GMAD WinRAR or 7zip, (I don't know how 7zip works, sorry about that)
In this guide, I will use GMAD and WinRAR.
First off, let's start with downloading the desired add-on, in this guide I used Resident Evil - Vector Playermodel. First download it by pressing subscribe, like this.
Not too hard, right?
Then we must open the GMOD folder, it's easiest to do like this.
Then goto Local files and press Browse local files.
Now it should look like this. Into garrysmod.
Then into addons.
Then it should look like this.
Then use CTRL + F to find the addon, usually it's the name.
Copy and paste, where you extracted GMAD.exe to, then run GMAD.exe
Materials
New Folder
Model
The zip.
Then you're done!
Now you just need to either share it on dropbox, if dropbox doesn't show up, which it sometimes does, use googledrive.
