Troubleshooting
Settings are not updated
If after editing your setting you don't see any change:
Deactivate or clear or rebake Simulation Cache
Move Timeline Cursor to Frame 0
Replay the simulation
To see your Simulation Cache, select the object with your Laser System and go to the Physics Panel:
Un-check "Cache" to disable Cache. Be aware that it will make your animation slower and in many cases you should re-enable it once your config is completed.
If you just want to actualize your Cache, just click on "Bake", and wait a few seconds.
If you want to clear you current Simulation Cache, just press the Trash icon.
Recommended workflow is to disable Simulation Cache during first configurations, and bake it once you're satisfied, to facilitate navigating through your animation.
I don't see my Lasers when moving the Timeline
Enable Simulation Cache and bake your Simulation Nodes.
Select Object containing Laser System you want to Bake, go to the Physics Panel, check "Cache", press "Bake" and wait.
My Object has disappeared
If you added Laser System directly on your Object, or if you have multiple Laser Systems on the same object, you have to enable "Display Geometry".
Motion Blur is not working
Unfortunately, this is a known issue. At the moment, Blender does not offer a way to properly handle Motion Blur with this kind of setup.
The solution for now is to use a different View Layer for your Lasers, and add a Vector Blur for your other(s) View Layer(s).
Actually, this is how the trailer has been made:
