TrailMesh allows you to add 3D trails via an emitter (TrailEmitter), have the shape defined by a curve and colored with a gradient.
Used to implement continuous trails, where an emitter is attached to a physics body which leaves a trail behind when it is moved (for example missile or airplane trails).
Caveats:
- Does not yet work in editor
- Visibility is a bit buggy
- Editor missing UI hints

- Add the trail emitter as a child of the object. This could be a ship, a character, a sword, or a projectile.
- In the inspector, set the
GeometryNodepathto some parent of the object. Usually, this will be your root node for the scene.
- Move the object during
