  Solid not glowing properly, mask is off-centre

  Posted by Andy Ho on November 15, 2015 at 3:50 am

  I am trying to made a solid glow, but the edges are never affected by the glow. I’m pretty sure it’s suppose to. How can I make the edges go together with the glow? Other objects like fire glow perfectly, but not a solid?

  

  For some reason my mask is off-centre and I seriously don’t know how to fix this problem…

  Glow: Do you mean how it has “less” glow at the corners? The way glow works is it blurs horizontal then vertical, so you are going to end up with a darkening at sharp corners, especially at this horizontal/vertical angle. To overcome this, you can duplicate your rectangular solid, add a mask expansion of half your desired Glow and the Gaussian Blur the full amount of the Glow. (i.e. use Mask expansion and Blur instead of Glow).

  Mask: Create the mask on a separate layer that doesn’t have the other effects (Stereo Mixer and Warp Stabilizer) applied and use it at a track matte. One or the other (or both) of the Effects are the culprit for the mask offset.
