CloseAccess the Particle System trails module.
This module adds trails to your particles. Trails can either be left in the wake of particles as they move, or can connect each particle in the system together.

using UnityEngine; using System.Collections;
public class ExampleClass : MonoBehaviour { void Start() { ParticleSystem ps = GetComponent<ParticleSystem>(); var trails = ps.trails; trails.enabled = true; trails.ratio = 0.5f; } }
attachRibbonsToTransform | Adds an extra position to each ribbon, connecting it to the location of the Transform Component. |
colorOverLifetime | The gradient controlling the trail colors during the lifetime of the attached particle. |
colorOverTrail | The gradient controlling the trail colors over the length of the trail. |
dieWithParticles | If enabled, Trails will disappear immediately when their owning particle dies. Otherwise, the trail will persist until all its points have naturally expired, based on its lifetime. |
enabled | Enable/disable the Trail module. |
generateLightingData | Configures the trails to generate Normals and Tangents. With this data, Scene lighting can affect the trails via Normal Maps and the Unity Standard Shader, or your own custom-built Shaders. |
inheritParticleColor | Toggle whether the trail will inherit the particle color as its starting color. |
lifetime | The curve describing the trail lifetime, throughout the lifetime of the particle. |
lifetimeMultiplier | Change the lifetime multiplier. |
minVertexDistance | Set the minimum distance each trail can travel before a new vertex is added to it. |
mode | Choose how particle trails are generated. |
ratio | Choose what proportion of particles will receive a trail. |
ribbonCount | Select how many lines to create through the Particle System. |
shadowBias | Apply a shadow bias to prevent self-shadowing artifacts. The specified value is the proportion of the trail width at each segment. |
sizeAffectsLifetime | Set whether the particle size will act as a multiplier on top of the trail lifetime. |
sizeAffectsWidth | Set whether the particle size will act as a multiplier on top of the trail width. |
splitSubEmitterRibbons | When used on a sub emitter, ribbons will connect particles from each parent particle independently. |
textureMode | Choose whether the U coordinate of the trail texture is tiled or stretched. |
widthOverTrail | The curve describing the width, of each trail point. |
widthOverTrailMultiplier | Change the width multiplier. |
worldSpace | Drop new trail points in world space, regardless of Particle System Simulation Space. |
