There is no vapor on f-15e's wingsi

[iceagre]

I can't find vapor on f-15e's wings. Is there any problem with my settings?

Works fine for me.

For me, when I fly the F-15E in the first mission after starting the game, the vapors works fine, but when I exit the mission and launch the second time without turning off the game, the vapors disappear.

Pat21, I am having the same problem.  The wing vapor shows fine on the first flight but nothing shows after except the wing tip contrails on the edges when the wings move or when you turn.
