Hello Everyone ! I need some help. I was trying to achieve the same effect for the ball tail used in Balls Race game by Ketchapp but didn't succeed. Here the reference link: https://itunes.apple.com/app/balls-race/id1326677737

At first i thought it was the Trail renderer but trail did not work or maybe i was doing it wrong. Can anyone please tell me how i will get that same effect? Thanks.,Hey everyone! I need some help.
