    I've been trying to make an object (let's say a Cube), leave a trail on a plane when it moves (it will only move forward and rotate).
    The question is, what would be the best way to draw a simple trail (like the one pictured in the attached photo), that would use the fewest resources?

    Thank you!

    the trail system is 2d (it turns to face cam), you need a ribbon system to lay 'track' down like tire skids that lay flat...., but the system(s) will stretch your texture they lock UV's to 0-1 never lerp or generate overlapping UV tiles

    asset store has better trails/ribbons at the moment,



    i forget if 5.5 is adding these features

    5.5 adds local space lines/trails. I.e. They don't face the camera. Maybe it will help :)

    Is there any other way to draw the trail without using the built-in TrailRenderer?
    The reason I'm asking is because the TrailRenderer is not that smooth when it comes to turning/rotating, leaving some 'spikes' when rotating at a low speed.
