@GavinsBeard added them to the dlclist? Can you spawn it via model name?

Probably has something to do with the popcycle.dat and the popgroups.ymt, but I don't know how to edit them. Maybe someone else?

It is possible, yes, Ive seen some people doing that, but I'm not really into modding itself so i cant help you out with it

@Dorian138 maybe also try using different gameconfigs and uninstall certain add-ons you maybe dont absolutely need, worked out for me with all my modded GTAs. What mod have you added till it stopped working?

@Jthom You probably found it already, but OpenIV also has a search function, you can use this in the future

Ok so,
as far as I think, that would hardly work because having everything loaded would take up quite a lot of graphics power etc.

If you've got enough power to do that, maybe try setting it in the tree model model files, or somthing like that. (dont really know what im talking bout)

If you have a modded GTA, you probably don't have the newest GTA version. Update your GTA via Steam and you should be good (if you used a mods folder you can do that, if you didn't then the new cars won't work, bc if you "update" the game via Steam, it also replaces the "broken" (modded) cars, sounds etc.)

Uhm I think nobody has understood your question.

If you want to have them added to the game but also let them spawn, you have to edit the "popcycle.dat" and the "popgroups.ymt" or however they're called.

Ok so,
I've been working on all those skins you can see below for some time now. The boxcar liveries are already released, and maybe I'm gonna release the other repaints soon, but there are 2 things keeping them from getting released: Laziness and no time. Maybe I'll have time to test everything, add more roadnumbers and weathering and so on. However, here are some pics:

Thanks!
