@Reyser I thought I could leave out the carols.meta completely.... oops! Do you think that was why I wasn't seeing any option for LSC? I think you can see my goal is that all the cars I add-in just have the "standard" modding options, like bulletproof tires, engine upgrade, turbo, etc.
Also, is there a default setting for lights? What should I do if the headlights on an add-in car don't seem to work right (i.e. the light appears on the roof of tunnels instead of a cone lighting the ground in front of the vehicle). I can link a screenshot if you need to see it. Should each car have its own light settings, or can they all share a general one? If so where should I define that?
Thank you again for all your help dude. I want to release this mod back to the community when I finish it and you definitely deserve credit.
