My ship doesn't have any impulse trails anymore... Or a warp out effect.
Is there a graphic setting that I may have inadvertently turned off by accident?
Any help would be appreciated!
The only "impulse effect" I know of comes from the engines of the Aegis set. Did you posibly change those out recently? If not press U goto your ship tab and right click on the engines, look for an "enable visuals" option
From my playing with the settings, it's the "vfx quality" that affects the appearance of trails (except Aegis, Borg and Breen that seem to appear all the time, unless disabled manually on the engine itself).
If you choose "high", trails will appear. Any lower quality won't show them.
Note that the change in trails appearing and disappeaing takes effect after logging out/back in.
