I'm very very new to combustion so please excuse my newbness. I'm trying to composite some sparks onto footage of a blade scraping the ground as it moves along. I'm using the basic Sparks particle control from the Fiery Light library. I'm trying to get the spark streaks to arc, so that they're not just shooting straight out, but have some weight to them so as they come out they go down towards the ground. I saw the weight dials in the emitter and behavior tabs, but even when i crank these way up, there seems to be no effect at all on the streaks themselves. I notice that the weight has an effect on the sparks, but not the streaks. Could someone shed some light on this? I must be missing something. I've been through the help files and the user's guide to no avail. I appreciate your time and patience.
