Hi guys! Need your advice I want to draw smokes in fllightgear but I make it on vertex and fragment programs so I make it on different ssgRoot so I have for example latitude and longitude and altitude of smoke. I convert it to cartesian coordinates Point3D center=sgGeodToCart(lat,lon,alt); so I have transform node on smoke after I make coordinates sgSetCoord(&tptpos,center.x(),center.y().center.z(),0,0,0); smoketransform->SetTransform(&tptpos); but I haven't seen my smoke :(( What I did wrong? Thanx in advance Bye
