Show customized car on Paintjob preview

Hi,

I’ve made some cool paintjob but when I share them, they always appear with the stock version of the car, I wanted to know how to put a customised car (like with a rocket bunny kit) on the preview of the paintjob :wink:

Seriously? Nobody to tell me how to share my car with a customised kit?
