I need help to fix my file names and hierarchy on ZModeler PLEASE

[George Spartan 0]

Hi, I just started using ZModeler yesterday! 

I am working on a model currently, and I just assembled some lights, a rambar, and all on a 2018 charger I found here:
https://www.modding-forum.com/forums/thread/189-2018-dodge-charger-pursuit-dev-awd-package-added-1-2a/

Anyway, I want to test it on my game, but every time I spawn it, it just crashes the game. I am presuming that this happens because the files are not set properly and things aren't named properly. I am really new, and I have no idea how to get a hierarchy setup or what to name what. Here's my hierarchy, hopefully somebody can give me a hand, it would be much appreciate to share y'all's knowledge! Thanks in advance!!!

So it starts with 2 sections, being lights and chassis (I think that I recall someone saying that everything should be under chassis but idk what to put, the whole "lights" folder i created or everything that's in it.

Have an amazing day!
