Lighting plays a crucial role in the 3D environment of Adobe After Effects. It can bring your scene to life, add depth, and help set the mood or focus. If you’re working with 3D layers and want to make your compositions more dynamic, learning how to use 3D Lights in After Effects is essential.
In this guide, we’ll cover everything from types of lights to setup, real-world uses, and pro tips.
🔍 What Are 3D Lights in Adobe After Effects?
In After Effects, 3D lights are used to simulate real-world lighting. Once a layer is turned into a 3D layer, it can be affected by lights and shadows, just like in 3D animation software.
Lights in After Effects affect the color, brightness, and shadows of your 3D layers. They do not affect 2D layers, unless those are made to interact via blending or other techniques.
💡 Types of Lights in After Effects
You can add 3D lights by going to:
Layer > New > Light
There are 4 types of lights:
1. Parallel Light
-
Emits straight rays like sunlight.
-
Doesn’t decay over distance.
-
Ideal for outdoor or uniform lighting.
2. Spot Light
-
Focused light beam with a cone angle.
-
Produces realistic shadows.
-
Great for stage or focused lighting.
3. Point Light
-
Emits light in all directions (like a light bulb).
-
Shadows cast in multiple directions.
-
Best for indoor, ambient lighting.
4. Ambient Light
-
Adds global light without casting shadows.
-
Good for lifting darkness but not for realism.
🧰 How to Add & Control Lights – Step-by-Step
✅ Step 1: Convert Layers to 3D
-
Select your layer
-
Click the 3D Layer switch (cube icon)
✅ Step 2: Create a New Light
-
Go to Layer > New > Light
-
Choose the light type (Spot, Point, etc.)
-
Customize Intensity, Cone Angle, Falloff, Shadow Darkness, etc.
✅ Step 3: Adjust Light Properties
-
Use the light gizmo in the composition panel.
-
Or, go to the Timeline > Light layer > Transform to reposition.
-
Tweak settings like Intensity, Shadow Darkness, Shadow Diffusion for realism.
🌑 Enable Shadows & Light Interaction
To see realistic effects:
-
Enable Cast Shadows on 3D layers (Layer > Material Options)
-
Set Accepts Lights and Accepts Shadows to “On”
-
Enable shadows in the Light layer settings
💬 Real Use Cases
-
🔦 Spotlight in music videos
-
🌇 Sunset lighting in animation
-
💼 Product showcases with soft lights
-
🌌 Sci-fi space scenes with ambient & point lights
🎯 Pro Tips
-
Use multiple light types for realism.
-
Combine Spot + Ambient for controlled yet filled lighting.
-
Use Falloff for natural distance decay.
-
Shadows add realism—play with Shadow Diffusion.
-
Add Light Falloff to mimic natural lighting (Inverse Square Law).
🧪 Bonus: Use Lights with Cameras
Lights are most powerful when paired with 3D cameras. Together, they give depth, cinematic movement, and immersive storytelling potential.
