Hi, 

I'm expericing some problems with the PMSG MD-11 and NGX. I have the wingtip vaportrail black. in both aircraft.cfgs, under the section effects I got for both:

 

vaportrail_l=fx_dummy
vaportrail_r=fx_dummy

 

but if I go in my MSFSX effects folder the file fx_dummy.fx is present, so I don't know what could be the problem. here some images

I'm guessing you've installed some other program that overwrote the files.

No, your winglets are simply on fire :-D

I'm guessing you've installed some other program that overwrote the files.

 

you said the magic words "overwrote the files" I remembered that I made a backup copy of a fresh install of FSX+ACC pack, so I restored the original fx_dummy.fx, the result? now there are no vaportrail, they're simply disappeared. the original one was 1.23kb, the "black" one was 1.26kb. Please, could you kindly check your file?

 

now there are no vaportrail, they're simply disappeared.

 

The effect is not a real effect.  It's a placeholder.  This is straight from Microsoft:

An existing effect can be disabled by replacing it with fx_dummy.fx, which is an empty effect.

 

If that vaportrail entry was from PMDG, then they added that in to make sure the aircraft would make no vapor trail when flying.  I don't recall ever seeing a vaportrail with the MD-11, but I haven't flown it in a while.

I have a vanilla install of the MD-11 and I have never hade any visible vaportrails.

 

Cheers,

ok, problem solved, thank you for you patience

PMDG sure makes some smokin' hot airplanes!!!
