I know I've mentioned that before, but does anyone know how I might implement a simple frame echo / trails effect, either in VDMX alone, or using a combination of VDMX and Quartz Composer?
I'm trying to create an oscilloscope-type effect, so I have a white blob that moves across the screen from left to right. What I want is for the blob to leave a trail behind it, that gradually fades to nothing (or complete transparency, preferably). The VVMotionblur plugin approximates what I want, but seems to leave a faint grey line behind it, that doesn't go away. I've noticed a similar effect with the RGB Trails plugin, incidentally.
Also, at higher VVMotionblur 'amount' values, the line becomes too faint.
Anyone know of an alternative way of achieving this very simple effect?
Cheers,
