This is a sample particle sparks object. Load it up and scale it with particle blur enabled and you will get sparks that appear to decay over time (just like the real thing). You can change the surface colors and falloff values as appropriate for your application. Have fun. %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% % \ / Mark Thompson Concurrent Computer % % -== Radiant ==- mark@westford.ccur.com 3D Graphics hardware % % / Image \ (603) 424-1829 architect and general % % Productions (508) 392-2480 nuisance % % % ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
