Would like to know if any of you have managed to implement the famous vapour trails effects when taking off and between 150-175 knots on the LevelD 763. I have it on my PMDG 737-800s and look spectacular on approach and landings.

Try asking here:http://www.leveldsim.com/forumsOn that note, however, has anyone found an .fx file for the water vapour that you see billowing behind the aeroplane if it's raining or the runway's wet?
