Scrolling grass and trees in portrait driving game top to bottom "how to question."

hzapps

Aloha all,

I am working on a portrait driving game where the vehicle is staying in one position mad the landscaping, grass trees will appear over the ridge and scroll down to bottom and disappear as they run off bottom of screen.

How do I make the landscape scroll or wrap from top to bottom at say anslight angle so that it appears the road is getting bigger as it gets closer to car?

Should I use interpolate to make the trees get slightly larger as the come more in to view and get closer to car

Thank you all
Mike
