particleIllusion now available for Sony Vegas if anyone is interested.

Have been playing with the trial version. Very impressive - except that I can't get the effects to overlay on any media, be it video or stills. Against a black background it's fine. I've tried all settings of Alpha channels, but no luck...

Robin in the settings under 'Emitters' is the option 'Composite' set that to 'Over background'.

Hi Nicholas,
Yes, I've seen and tried all the settings and still nothing works. Mind you, I'm still having the same problem with NewBlue Titler Pro: not being able to render out, even though PC and graphic card are both up to spec...
I might download the Standalone version of ParticleIllusion and see if that works.

Well, finally managed to solve both problems - ParticleIllusion and NewBlue Titler Pro.
I checked the properties settings for Vegas Pro and saw that I had opted to run application as Administrator. I reverted to the normal mode and then everything worked! Don't ask me what difference it should make, but I'm happy again...
