Add glowing effect to make highlights bloom — it’s perfect for sci-fi, neon, or anything that needs extra polish in After Effects.
Steps to add glowing effect
Select your layer and go to Effect → Stylize → Glow.

Lower Threshold to include more pixels in the glow, raise Radius to spread it out further, and adjust Intensity to control how strong the glow appears.

Stack multiple Glow effects with different values for richer, more layered results.

One more thing
Precompose complex layers first, then apply Glow for cleaner edges and better performance.
