Hey Mark,

Thanks, but Unmult is what I am using to fix this, but it doesn’t look as good as I want, when my metalic object comes in from off-screen, you can see through some of it’s surfaces, it’s not bad but it ain’t perfect. Here’s what I posted on the Adobe forum, but got no answers. There has to be a way to get this filter to use my alpha channel!

“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 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?”

Maybe this begs the question, “how do I master the Pixel Chooser” as I can’t figure it out for the life of me. Tried some of the presets and see how they work, read the manual three times, can’t figure it out.

Hi,

In BCC Glint, you need to set the alpha channel within the filter – in AE, precomp the Invigorator effect, then add the BCC Glint to the precomp and set the Glint background layer function to the precomp.

Cheers,

Peter.

Thanks Peter, I’ll try that.

I tried this pre-comp idea but can’t seem to get it to work. I was wondering if you could give a more detailed explanation of this. I am very frustrated at the dificulty of using BCC5 open GL filters. They look great but are very cumbersome.

I appreciate your help though.
