  • Use IES profiles for realism: Apply IES textures to mimic real-world light distribution and intensity.
  • Layer lights for depth: Combine directional, point, and spot lights to enhance scene dimensionality.

Why This Matters

Imagine you’ve just finished building a stunning environment in Unreal Engine 5—lush forests, futuristic cities, or cozy interiors. But something’s off. It feels flat. Lifeless. That’s because lighting is the heartbeat of any scene. Without proper lighting, even the most detailed assets look like cardboard cutouts.

Lighting doesn’t just illuminate—it sets mood, guides attention, and makes your world feel real. Whether you’re crafting a horror game where shadows creep or a sunny open-world adventure, knowing how to add lights in Unreal Engine 5 in 2026 is non-negotiable. And the good news? It’s easier than you think—once you know the right steps.

I remember my first project where I slapped in a single directional light and called it a day. The result? A washed-out mess. Since then, I’ve learned that lighting is both art and science. In this guide, I’ll walk you through everything you need to know to light your scenes like a pro—no jargon, no fluff, just real-world tips that work.

What You Need

Before we dive in, let’s make sure you’re set up for success. You don’t need fancy hardware or expensive plugins—just the basics:

  • Unreal Engine 5.3 or later (the latest version ensures access to Lumen and Nanite optimizations)
  • A scene with at least one static or movable object (walls, props, terrain—anything to cast shadows)
  • Basic familiarity with the Unreal Editor interface (Viewport, Details panel, Place Actors menu)
  • Patience and a willingness to tweak settings—lighting is iterative!

Optional but helpful: A reference image or mood board. Lighting is emotional. Knowing whether you want a warm sunrise or cold moonlight helps you choose the right tools faster.

Step-by-Step Guide to How to Add Lights in Unreal Engine 5 in 2026

Step 1: Open Your Level and Access the Place Actors Menu

Start by opening your project in Unreal Engine 5. Navigate to the level where you want to add lighting. If you’re starting fresh, create a new level or use one of the starter templates (like “Default” or “Archviz”).

Now, look for the Place Actors panel—usually on the left side of the screen. If it’s not visible, go to Window > Place Actors to enable it. Click the Lighting category. You’ll see icons for different light types: Directional Light, Point Light, Spot Light, and Rect Light.

Each serves a different purpose, so don’t just grab the first one. Think about your scene: Do you need sunlight? A lamp? A flashlight? We’ll cover each type in a moment.

Step 2: Choose the Right Light Type for Your Scene

Not all lights are created equal. Here’s a quick breakdown of the main types and when to use them:

  • Directional Light: Mimics the sun. Use it for outdoor scenes or large indoor spaces with consistent lighting. It casts parallel rays and affects the entire level.
  • Point Light: Emits light in all directions from a single point—like a bare bulb. Great for lamps, ceiling lights, or glowing orbs.
  • Spot Light: Projects a cone of light, like a flashlight or stage spotlight. Perfect for focused illumination or dramatic effects.
  • Rect Light: Emits light from a flat surface, like a fluorescent panel or window. Ideal for soft, even lighting in interiors.

For most beginners, I recommend starting with a Directional Light for overall illumination, then adding Point or Spot Lights for detail. In my early days, I overused Point Lights and ended up with a disco effect. Balance is key.

Step 3: Place and Position Your Light

Click on the light type you want, then click anywhere in your viewport to place it. Don’t worry about perfection yet—you’ll adjust it in the next step.

Use the translation (move), rotation, and scale gizmos to position your light. For example, if you’re using a Directional Light to simulate the sun, rotate it so the light hits your scene at a natural angle—say, 45 degrees from the horizon.

Pro tip: Hold Ctrl + Shift + Click on an object to snap your light to its surface. This is super handy for placing lamps on tables or ceiling fixtures.

Step 4: Adjust Light Settings in the Details Panel

With your light selected, open the Details panel (usually on the right). This is where the magic happens. Here are the key settings to tweak:

  • Intensity: Controls how bright the light is. Measured in lumens (for Point/Spot/Rect) or lux (for Directional). Start low—500 to 2000 is often enough.
  • Temperature: Sets the color warmth. 6500K is neutral white (like daylight), while 3000K is warm (like incandescent bulbs). Use this to match your scene’s mood.
  • Light Color: Overrides temperature with a custom color. Great for neon signs or magical effects.
  • Cast Shadows: Make sure this is enabled (it usually is by default). Shadows add depth and realism.
  • Source Radius: Affects shadow softness. Larger radius = softer shadows. Crucial for avoiding harsh, video-gamey edges.

I once spent hours wondering why my shadows looked pixelated. Turned out I had Source Radius set to 0. Bumping it to 5–10 fixed it instantly.

Step 5: Enable and Optimize Lumen for Real-Time Global Illumination

Unreal Engine 5’s Lumen system is a game-changer. It provides real-time global illumination—meaning light bounces naturally off surfaces, creating realistic indirect lighting without baking.

To use Lumen, go to Project Settings > Rendering > Global Illumination and set it to Lumen. Also enable Hardware Ray Tracing if your GPU supports it (RTX 20-series or newer).

Once enabled, your lights will interact dynamically. Move a light, and the bounced light updates in real time. It’s like having a lighting artist on speed dial.

But be warned: Lumen can be demanding. If your scene lags, reduce Lumen Scene Detail or use Stationary lights instead of Movable ones for less dynamic objects.

Step 6: Test and Iterate in Real Time

Don’t set it and forget it. Lighting is all about iteration. Hit Play or use Simulate to see how your lights look in-game. Walk around, check corners, and look for overexposed areas or missing shadows.

Use the Visualize > Buffer Visualization > Lighting Only mode to see just the lighting contribution. This helps spot imbalances.

I always keep a notepad nearby to jot down adjustments: “Move kitchen light 10 units left,” “Reduce intensity by 20%.” Small tweaks make a big difference.

Pro Tips & Common Mistakes to Avoid

Pro Tip: Use IES Profiles for realistic light falloff. These are photometric data files that mimic real-world fixtures. You can find free ones online or create your own. They make Point and Spot Lights look incredibly authentic.

Warning: Don’t rely solely on Lumen for everything. While it’s powerful, baked lighting (using Lightmass) still has its place—especially for static scenes where performance matters. Mix both for best results.

One mistake I see often? Overlighting. More lights ≠ better lighting. In fact, too many lights can cause performance issues and visual clutter. Stick to a few well-placed sources.

Another common error: ignoring light mobility. Use Static lights for non-moving objects (walls, floors), Stationary for fixed lights that don’t move but can change intensity/color, and Movable only for dynamic lights (like a player-held torch). Misusing these can break Lumen or cause lighting artifacts.

And please—don’t skip post-processing. Add a Post Process Volume and tweak exposure, bloom, and contrast. It ties your lighting together and makes everything pop.

FAQs About How to Add Lights in Unreal Engine 5 in 2026

Q: Can I use real-time lights in a mobile game?
A: Yes, but with caution. Real-time lights (especially Movable ones) are expensive on mobile. Use baked lighting where possible, and limit dynamic lights to essential elements like player flashlights.

Q: Why are my shadows pixelated or blocky?
A: This is usually due to low shadow map resolution or a Source Radius set too low. Increase the Shadow Map Resolution in the light’s settings and bump up the Source Radius for softer edges.

Q: How do I make lights flicker or animate?
A: Use Blueprints! Create a simple timeline that varies the light’s intensity over time. Or use a Material Parameter with a sine wave function for smooth flickering.

Q: Can I import lights from other software?
A: Not directly. Lights aren’t typically exported with models. You’ll need to recreate them in Unreal. But you can use reference images or lighting data to match your original setup.

Q: What’s the best way to light an interior scene?
A: Start with a Directional Light for ambient fill, then add Rect Lights for windows or ceiling panels. Use Point Lights for lamps and Spot Lights for accent lighting. Enable Lumen for realistic bounce light.

Q: How do I reduce lighting performance cost?
A: Use fewer Movable lights, increase light culling distances, and bake static lighting. Also, lower Lumen settings if needed. Always test on your target platform.

Final Thoughts

Mastering how to add lights in Unreal Engine 5 in 2026 isn’t about memorizing settings—it’s about understanding how light behaves in the real world and translating that into your digital scenes. Start simple, experiment often, and don’t be afraid to break things. Some of my best lighting setups came from happy accidents.

Remember: lighting is storytelling. A single well-placed spotlight can draw the player’s eye to a key item. A dim, flickering bulb can build tension. Use your lights with intention.

Now go light up your world—one shadow, one glow, one perfectly timed bounce at a time.
