I'm trying to make some explosions but I'm not very good at it, so hints are welcome. While the basic animation and the individual renders don't look too bad, I can't get a good-looking rendered animation. In particular there are mysterious flickers where the rolling motion jumps from one frame to another. I'm also interested in how to control the explosiveness. At the moment I do it mainly via animating the fuel and smoke emission. Preview animation: Low framerate render: normal fp
