Background is 16x9 format. Using Fat Beams of Light (Elvis Deane) and trying to add a deflector to stop effect from crossing top and bottom black bars. Can't seem to deflect anything. Is there an easier fix when using wide-screen footage? I've tried resizing but the result isn't stunning. Running SE. Thanks!
There's no way to do this easily in SE, since it doesn't have Blocker objects. The only way I could think of within pI is to make an emitter that's simply a black square, and position it over the top and bottom of the screen to act as masks. You may have to duplicate additional particle types to keep the square entirely opaque if Motion Blur is turned on.
