In-game resources are a really good place to start.

mods\update\x64\dlcpacks... Should be a eup folder. If not reinstall.

That makes a lot of sense.

The vest is great. But you could probably shuffle some things to more efficient places. A taser would work in that placement but a cross-draw setup is much more common. The cuffs like someone else mentioned, block the scissors. If you were to move the cuffs to the back or right side (from the front on view) that would be much more efficient for a officer. Another thing that you could do is remove the pistol mags on the top and replace them with the cuffs. Pistol mags that high would probably be super clunky to remove especially quickly in a long shootout and might result in someone punching themselves in the face (would be very funny to see). Overall though good work and progress made so far :). It can take a while, so don't get discouraged and remember that you won't be an ace modeler to begin with so it's fine if you very first models look like shit, you're learning. Some more advice for actually modelling, when creating something real it is important to get as much research as possible (length, height, width, TONS of photos etc.) Take your time.

Firstly I would recommend how to 3D model using something like blender. It's free and can allow you to edit and add to your models freely. It also give you the knowledge on how everything works in the modeling field and can make it a bit easier to work with zmodeler (which can be a giant pain). The main thing to learn is Zmodeler 3, which is used to put all your models into GTA. It also allows you to create cars and stuff like that. You can find tutorials for bender but it's kinda of a mixed bag when it comes to Zmodeler. I wish you the best on your endeavours, and if you need any advice or any more detail feel free to PM me. I'm sure HANAKO can give you their take on it as well.
