They're not bad, but aren't they a little too bright for too long a period? I like how they trail off, (much better than stock) but it seems to me there's too much bright turbulence in the wake for way too long. Of course, I don't know what speed the ships are going, so if they're at flank then these would be perfect....
How do the wakes look when the ship is moving at 1/3? Thanks for your help and your mod work!
