well that's further than i had gotten. i'll have to see if their are videos on how it works. I think Pop The Hood was done in Unity.
yes you saw the video I posted back in 2016.
I wish I could get my hands on the unity code that have already been started that resulted in pop the hood and other demos (seems to remember something about the car being able to drive in and out of the garage)
that way I might be able to continue the development from there
