I separated my scene into render layers and moved the rendered frames into the compositor.
When I combine them using Alpha Over, I get very strong glowing from my dust layer (dust image as plane) and I can’t properly remove it with color correction.

When I render the full frame normally (Render Image), this glow naturally blends with the sky and looks correct.

Is there any way to fix this in the compositor? I really don’t want to re-render all 300 frames again.

The image with the snow is a normal full-frame render and it looks correct.
The shot with the spaceship is my animation that I split into separate layers/passes, and that’s where the glow issue appears after compositing them together.
