I made an upgraded version of the 2.0 liter engine from the sunburst as well as attempted to steal the awesome new exhaust from the Vivace Rally so I can get the awesome pops from that thing on the sunburst. (I'm just not into hatchbacks lol) This is literally my first attempt at a mod, and pretty much coding in general. I've only messed with it a little bit. I've been browsing the forums and online guides and the wiki for at least 4 hours. I'll upload the currently broken version and see if you guys can figure out what is going on. It appears in my mods list but neither the JKS exhaust or the BJ25 engine appear as possible configs when customizing the sunburst. I've even compared my mod to mods that I use that work, and I can't tell what makes mine different and wrong when compared to theirs. Thanks for any help.
It looks like you're folders are messed up. In order for the sunburst to recognize it as a part it should be like this NewSunburstMotor > vehicles > sunburst> files... this should work:
Doh! Thanks so much, I realized just now that every time I zip the folder, it would make it (x).zip with a file inside called (x) when it's supposed to be (x).zip then vehicles, happens every time I try to zip. I'll have to zip the vehicles file now and then rename vehicles.zip to (x).zip which will contain the vehicles file. Thanks for fixing my mistake.
