ParticleSystem.TrailModule.ribbonCount

Description

Select how many lines to create through the Particle System.

For example, if using 1 ribbon, a single line is drawn, starting at the youngest particle, and travelling through each subsequent particle based on their ages, until finally reaching the oldest. If using a value larger than 1, multiple lines are drawn, connecting each Nth oldest particle. For example, is using 3 ribbons, every 3rd particle is connected (1,4,7, and 2,5,8 and 3,6,9).
