Some particles can even change appearance during their live. Each object can emit particles. You can add particle effects to  Effects  property. Each effect then has its own PFX manager and PFX renderer. GLCustomPFXManager [TODO] GLPolygonPFXManager Polygon particles are made up of circular array of triangular polygons always facing camera. Polygons use vertex colors. You can specify inner and outer color for the particle. Outer color is usually transparent. Each polygon is opaque in the center of the particle and gradually becomes transparent towards the edge.
