Hello:I know I have seen this somewhere, but a search hasn't helped me. I noticed recently that on approach(during replay) that my aircraft are trailing what looks like smoke straight down toward the ground and even when on the ground. This is not the same as the snow effect that FS has during the winter in the north. I don't remember when it started. Like I said above, I have seen this on the forums before but, I don't know which one. Either way, a search of the forums got me nothing.Does anyone remember what the fix is for this?Thanks RichardS

HiIIRC this is caused by an addon aircraft which has loaded the fs2002 contrail effects file over the correct fs2004 one. You will need to go and get the correct fs2004 fx_contrail_l.fx and fx_contrail_s.fx files from whichever of the fs2004 disks has it on. You may need to trawl the .cab files until you find it. Naturally backup the ones in /effects/ just in case you want to revert.Good luckJames

to find the correct FS9 disk and cab file look a this wonderful www-page developed by Jim Robinson -http://www.cat-tamer.com/flightsim/faq001.html--

Scoob...thats a top drawer link. Such a simple but well-executed idea. Thanks for the heads up!Bookmarked :)

Thanks Guys:I will check that out. Actually I am having the problem in FSX but nobody over there answered my query. I hope that page will point me in the right direction for FSX too.RichardS
