The 1.4 series introduced significant control over how glows are generated and composited:
Version 1.4 added the ability to use alpha or luma masks to precisely define which parts of a layer emit light.
Uses an inverse square algorithm to simulate how light naturally dissipates, avoiding the "plastic" look of standard linear glows.
Includes gamma correction (to keep colors accurate in different color spaces), dithering (to prevent banding), and aspect ratio adjustments for anamorphic looks. Installation & Requirements
