I have a logo resolve with its accompanying logotype and a light flare on add mode moving across it. Logotype fades up from 0 opacity and starts blurred, ending sharp. I want to render with an alpha channel and retain the flare effect on the logo/logotype but lose the flare from outside the object. I’m making my own luma matte and trying to matte in the flare but it seems to strangle the edges when the type is blurred. Any suggestions on the correct way to do this?

Cheers.
