Lighting a Small Scene in Unreal Engine 5

Why Lighting Matters for a Small Playable Scene

Lighting is not just about making a level “look nice.” In a beginner gameplay scene, lighting should make the space readable: the player should quickly understand where they are, what is important, and where to go next. Good beginner lighting usually comes from a simple plan:

• One primary light direction that defines the scene’s main shadows and shapes.
• Controlled contrast so important areas are brighter or more visually distinct than unimportant areas.
• Eye guidance using bright spots, shadow framing, and color temperature to pull attention toward the path and goal.

Core Light Types You’ll Use

Directional Light (Sun/Moon)

A Directional Light acts like sunlight: it comes from one direction and affects the whole level. It creates strong, consistent shadows and is usually the main “key light” in outdoor scenes.

• Best for: outdoor daylight, moonlight, strong readable shadows.
• Gameplay benefit: a clear shadow direction helps players read slopes, steps, and object shapes.

Sky Light (Ambient Fill)

A Sky Light provides soft ambient lighting, filling in dark areas so shadows are not completely black. It helps you keep detail visible in shaded regions.

• Best for: outdoor ambient fill, indoor ambient bounce approximation.
• Gameplay benefit: prevents “crushed blacks” where players can’t see obstacles.

Point Light (Bulb/Omni Light)

A Point Light emits light in all directions from a point, like a bare bulb. It’s useful for small pools of light and highlighting interactable spaces.

• Best for: lamps, small highlights, accent lighting.
• Gameplay benefit: creates clear “islands” of visibility and can mark safe zones or points of interest.

Spot Light (Flashlight/Cone)

A Spot Light emits light in a cone, like a flashlight or a ceiling spotlight. It’s excellent for directing attention because it naturally creates a bright focal area.

• Best for: doorways, goal markers, dramatic focus.
• Gameplay benefit: strongly guides the player’s eye and can frame the intended route.

Readable Lighting for Gameplay: A Simple Checklist

1) Choose a Primary Light Direction

Pick one main direction that defines the scene. In outdoor scenes, this is your Directional Light. In indoor scenes, it might be a dominant Spot Light or a set of ceiling lights that all feel consistent.

• Keep the main direction consistent so the player can “read” the space quickly.
• Avoid having equally strong lights from multiple directions unless you want a flat look.

2) Control Contrast (Don’t Let Everything Be the Same Brightness)

If every area is evenly lit, the player has no visual priority. Instead:

• Make the path slightly brighter than surrounding areas.
• Make the goal the brightest (or most visually distinct) area in view.
• Keep non-play areas a bit darker or less saturated to reduce distraction.

3) Guide the Player’s Eye

Use lighting like arrows:

• Bright-to-bright stepping stones: small pools of light leading from start to goal.
• Framing with shadow: darker edges around a doorway or corridor make the opening feel important.
• Color temperature: warm light (orange/yellow) feels inviting; cool light (blue) feels distant/industrial. Use this to separate “safe start” vs “mysterious goal,” or vice versa.

Practical Setup: Sky/Atmosphere and Exposure Control

Outdoor Day Setup (Fast, Beginner-Friendly)

This approach assumes you want a simple daytime playable scene.

1. Directional Light: Place or select your Directional Light. Rotate it to set the sun angle. A lower angle (early morning/late afternoon) gives longer shadows that improve depth and readability.
2. Sky Atmosphere: Add a SkyAtmosphere actor if your level doesn’t already have one. This provides a believable sky and horizon scattering.
3. Sky Light: Add a SkyLight. Set it to capture the scene (often Real Time Capture is available; if not using real-time, recapture after major sky changes). The Sky Light prevents harsh black shadows.
4. Optional: Volumetric Clouds: Add VolumetricCloud only if you want cloud presence; keep it simple to avoid spending time tuning.

Indoor Setup (Simple “Room Lighting” Choice)

If your scene is indoors or mostly enclosed, you can still use a Directional Light (as “sun through windows”), but many beginner scenes work better with a few intentional artificial lights:

1. Use a Sky Light at low intensity to keep shadows readable.
2. Add Spot Lights for ceiling fixtures or corridor guidance.
3. Add Point Lights for lamps or small accent pools.
4. Keep one light as the “dominant” light so the scene doesn’t feel directionless.

Exposure Control (Stop the Scene From Auto-Brightening/Darkening)

Auto exposure can make playtesting confusing: you walk into a dark corner and the engine brightens it, reducing the contrast you intended. For beginner lighting, it’s often best to lock exposure while you tune.

1. Add a Post Process Volume to the level.
2. Enable Infinite Extent (Unbound) so it affects the whole scene.
3. In Exposure settings, set Metering Mode to a fixed approach (depending on your UE5 version/settings), or set Min/Max EV (or Min/Max Brightness) to the same value so exposure doesn’t adapt.
4. Play in-editor and confirm brightness stays consistent as you move.

Tip: Lock exposure while you build lighting. Later, you can re-enable gentle adaptation if you want, but only after your gameplay readability is solid.

Step-by-Step: Lighting a Small Scene With Clear Gameplay Readability

Step 1: Establish the Base Light

1. Decide: Day (outdoor) or Indoor.
2. Set your primary light direction (Directional Light for day; a dominant Spot/Directional for indoor).
3. Adjust intensity until the scene is clearly visible without needing extra lights everywhere.
4. Add/adjust the Sky Light so shadowed areas still show shape and obstacles.

Step 2: Create a Readable Path

1. Stand at the start area viewpoint (the player’s first camera view).
2. Identify the intended route. Add subtle lighting that “connects” the route visually.
3. Use Spot Lights to highlight doorways, ramps, or corridor turns.
4. Use Point Lights to create small pools of light at key decision points (like intersections).

Step 3: Make the Goal Visually Distinct

The goal should read as important from a distance or at least become increasingly obvious as the player approaches.

• Make the goal area brighter than nearby areas, or
• Use a different color temperature (e.g., warm goal in a cool environment), or
• Use a spotlight cone that naturally frames the goal object/doorway.

Step 4: Check Contrast and Avoid Common Beginner Problems

Mini-Exercise: Light the Start and Goal Differently (Then Playtest)

Goal of the Exercise

Create two distinct lighting “zones” so the player instantly understands where they begin and where they should go. Then confirm through playtesting that the intended path is visually clear without signs, text, or UI.

Part A: Light the Start Area (Safe, Clear, Welcoming)

1. At the start area, set a comfortable brightness level (not the brightest in the level).
2. Use a soft fill (Sky Light or a low-intensity Point Light) so the player can read nearby geometry immediately.
3. Add one subtle directional cue: a Spot Light aimed toward the first turn, doorway, or ramp.
4. Keep contrast moderate here: the player is orienting themselves.

Part B: Light the Goal Area (High Priority, Strong Focus)

1. At the goal area, create a stronger focal point using one of these methods:

• Brightness method: Add a Spot Light aimed at the goal object/door and make it the brightest local feature.
• Color method: Make the goal lighting warmer or cooler than the rest of the scene (subtle difference is enough).
• Silhouette method: Light behind or above the goal so it stands out against darker surroundings.

1. Reduce nearby distractions by lowering intensity on lights that pull attention away from the goal.

Part C: Playtest for Visual Clarity

1. Press Play and move from start to goal without using any objective markers.
2. Ask yourself these checks:

• From the start, can you guess the correct direction within 2–3 seconds?
• At intersections, does lighting naturally suggest the correct turn?
• Do you ever walk into a dark area because it looked like the path?
• Does the goal become more visually dominant as you approach?

1. Iterate with small changes:

• If the path is unclear, add a small pool of light at the next waypoint.
• If the scene is too bright everywhere, reduce fill and keep only key accents.
• If the goal doesn’t pop, increase its spotlight intensity slightly or narrow the cone angle to concentrate brightness.
