  • Some BCC filters don’t like (use) alpha channels by default?

    This was posted on the Adobe forum with no answers.

    You would think a filter set that costs as much as this one does would kinda work easily, not for me it doesn’t.

    I put the Glint filter on an Invigorator object, and it’s beautiful but it is ignoring the alpha channel. Screwing around with the Pixel Chooser is not helping, I wish that thing would just go away. Precomposing the Invigorator layer prior to adding the glints etc does not help. When I put AE resident glow filter and a few of the CC light filters on there is no problem. Trapcode’s Starglow filter works fine too. How the heck do you get this thing to work?

    The answer to this has to be in the pixel chooser, although every reference to alpha channels in the manual ain’t helped yet. I don’t understand how the PC works.

    NO, Unmult is not a satisfactory solution, this should work on it’s own.

    Hey Dave,

    I avtually used “add” yesterday on one of these glint files, it’s okay, about the same result as using Unmult and actually getting an alpha, in both cases the image is a bit washed out. Acceptable, but washed out.

    I did find an article online that explains how to use the Pixel Chooser, it is a useless tool IMO, and not good in this situation, where the object has to knock cleanly out of the background, To get it clean I lose the glints, a perfectly stupid tool. Why can’t there be an option to just use the alpha channel with this plugin that works, on or off? Can someone explain that to me? What a wast of time and money.
