The trail module is used to add a trail effect to the tail of the particle to achieve a trailing effect similar to the one in the following figure.
|Mode s||The way the particle system generates trailing, currently only supports Particles, which means that a trailing effect is formed on the motion track of each particle.|
|LifeTime||The lifetime of the generated trailing.|
|MinParticleDistance||The shortest distance that particles travel each time they generate a trailing node.|
|Space||Choose to run trailing based on World coordinate system (World) or Local coordinate system (Local)
(Custom is currently not supported)
|TextureMode||When a TrialMaterial texture is specified in the renderer module, the unwrapped form of the texture on the trail. Currently only Stretch is supported, which means to overlay the texture on the entire trail.|
|WidthFromParticle||Trail width follows particle size|
|WidthRatio||Trailing width. If WidthFromParticle is checked, the trailing width is the sample size multiplied by the ratio.|
|ColorFromParticle||Whether the trailing color follows the initial particle color|
|ColorOverTrail||The trail color changes with the length of the trail itself|
|ColorOvertime||trailing color changes over time|
Click the button to the right of the attribute input box, you can choose to edit the curve/gradient color of the attribute, please refer to Particle Property Editor.
