After Effects not revealing Alpha channel with layer set to add or screen

[chadw59613595]

After Effects 2024 is no longer revealing the alpha channel with layer mode is set to Add or Screen.  It WILL reveal the other layers within the project below a layer set to add or screen, but NOT the transparancy when there is no solid underneath.  Same effect in render.

The answer to anyone using Maxon / Red Giant apps is the uni.unmult plugin/effect found in RG Utilities (Maxon plugins).   Since After Effects 2024 stripped access to Knoll Light Factory which had unmult built in, this is the best workaround to make Real Lens Flares work while perserving an alpha channel.
