As the title suggests, I’m trying to create a ribbon of light behind my vehicle similar to the ribbon that appears behind a light cycle in Tron. I was initially thinking that a spline behind the vehicle would work but I’m thinking there has to be a more efficient way. The ribbon of light would need to be a solid mesh that allows for collision, and it would need to disappear at a certain length (for instance, after the ribbon of light reaches a distance of 1000cm, then the tail starts to disappear so that the total length of the ribbon stays at 1000cm max. Any suggestions as to how I can get started? Thanks!
