Emitter Visibility

[nskok]

If you haven’t added any ObiEmitterShape anywhere in the scene, the emitter will just be a point in space. Most sample scenes use either ObiEmitterShapeEdge or ObiEmitterShapeDisk. See:

You can have as many shapes connected to a single emitter as you want, the emitter will spawn particles from them all. Note that even if you have some shapes for your emitter, they're drawn as gizmos so they abide by the rules set in Unity's gizmos dropdown: if you have gizmo rendering disabled, they will be invisible.

Also keep in mind that scaling a emitter is no good in most cases: it will compress/expand the surface trough which particles are emitted, causing pressure spikes/gaps. Change the size of the emitter shape instead.

I have the emitter established as a sphere, and it does emit, but again cannot see the gizmo. The gizmo is enabled.
