Black Solids are now transparent?

For context, I'm working on a visual that has several sections of the video masked for alpha transparency, but the black areas that are not masked are still vital to maintaining color + texture with some of the overlays I'm using.

I just updated to AE 2025, and suddenly all of my black solid layers that were preserving the overlay in this project are now totally alpha/transparent and not functioning with the overlay as intended?

If you want to stick with Red Giant Universe/Glow, try uni.Chromatic Glow or uni.Edge Glow. All other Universe glows use every color on the layer and black generates 100% opacity in the alpha channel, while white generates 0% opacity.

The other option would be to add a black solid layer below the layer with uni.Glow layer, select both layers, then Pre-ccompose.

There are lots of other glows that will give you similar looks while preserving the black background.

UPDATE:

Have found the source of the problem - the Red Giant uni.Glow effect seems to be knocking out the black values for alpha. Probably something to take over to a Maxon forum, but thought I'd share this issue here as well

Check what the "Source Opacity" is set to. It's the second to last parameter for uni.Glow. If that's anything other than 100%, it starts to knock out the source that the effect is applied to.
