First look at the effect chart.
Figure 1
This is a static effect diagram.
Figure 2
Here's how to make the steps.
1, first create a missile object model, here do not do detailed introduction.
Figure 3
2, then create the particle system emitter and connect with the missile. The Emitte parameters are as follows: Rate =250,emitter Type =directional,spread=0.15,speed random = 4. Next, you create the directional light parameter, the intensity value is set to 0.63, and you add it to the scene and copy it to the diagram position.
Figure 4
3, set the Particle property parameters. Select the particle emitter (CTRL + a) and bring up the attribute, and adjust the Render attributes:particle Render type= Cloud (s/w) in the property bar ParticleShape1 under lifespan Attributes changed to lifespan mode=constant,lifespan=2. Set under Add Dynamic attributes: Color=add per particle attribute,opacity=add under particle attribute,general Tab: First fill in Add Ncandescencepp, finally add again into the RADIUSPP, in per particle (Array) attributes right click RADIUSPP under Creation Expression, Specify particleshape1,radiuspp=1.4, and press create.
