Now that we know a bit more about the particles and how to control them, we can add some objects and particle systems to the rear engine. The purpose of these particle systems is to create an effect of a combustion engine, dumping energy into outer space. To do that, we will use a mix of particles and nodes to create a glow effect. First, add a circle with the approximate same size of the opening for the engine at the back.
Make sure that the circle has several subdivisions on its faces; otherwise, our particle system won't work very well. When the circle is set and created, set up the particles with these settings:
Amount: 3000.0
Sta: 10.0
End: 90.0
Life: 80.0
Rand: 2.0
Change the initial velocity of the particles to 2 using the Normal force. With these parameters, we will have a particle system that looks exactly like the following screenshot:
The next step is to add some rotation to the system, and to do this, we will go to the Physics menu and choose the random...
