Go to your lomac folder....go to config/weapons then opent eh drawinfo.lua file...you have to edit the RGB values of the smoke...which smoke you edit depends on the color you want to overwrite...and the kind of smoke pod you want to overwrite...if you want this on a non Nato plane you have to edit the R73U's and if you want to edit the Nato plane smokepods you have to edit the ones labeled AIM-9S. Pick the smoke you want to overwrite and change the r, g, and b values all to 0 to get a black color for the smoke...
Hope this helps! :)
