Hi,as some-one posted how one can alter the rate of the strobe lighting by editing the appropriate effect file with wordpad,if was wondering if it is possbile to edit contrails.I opened the contrail_fx and the other one with wordpad but I couldn't come up with something.could any of you specialists take a look at it and see which parameters could influence the contrail (length,height at which is appears,...)

contrails are veery editable :Di changed them from lines to more "smoky" look. as u said just take wordpad and change them. why dont u get the effects SDK from microsofts insider page???? it helps very much.
