Michael, Video Post rules, OK? <G> >> the glow.ixp description in my ipas manual does not seem to indicate how to make a glow either grow or recede. << I don't think there is a one step process, but glows will naturally grow and recede when the are dissolved or faded in and out – it's there nature. They can't help it. Here's what I do: 1) render the scene *without* the glow 2) render the scene *with* glow in video post (VP) 3) composite in VP as follows: layer 1: the full animated scene layer 2: the glowed frame with fadeIN over n frames (2-5 looks good) layer 3: the glowed frame with fadeOUT over n frames (10 looks good) Try it and see. The above example would be an almost instant, burn-on type glow which slowly dies out – standard logo fare <g>. Make sure the fadeOUT layer starts after the fadeIN is complete. Looks like this: scen*.tga o——————————-o glow.tga fadeIN o–o glow.tga fadeOUT o——–o I hope this overblown example helps 🙂
