Lesson 8 gave your scene depth and dressing. Lesson 9 is where the environment starts to feel intentional: a lighting pass that supports readability, mood, and portfolio framing without crushing gameplay clarity.

Lesson Objective

By the end of this lesson you will have:

1. A repeatable key-fill-rim setup for your hero camera
2. An exposure and contrast baseline that keeps major shapes readable
3. A simple color script note you can reuse in engine and presentation shots

Step 1: Lock your lighting goal before touching lights

Write one sentence for the scene mood and one sentence for gameplay readability.

Example:

• Mood: "Warm dusk with calm but slightly mysterious atmosphere."
• Readability: "Main route and interactable doorway must stay visible from camera A and B."

This prevents random tweaking and keeps your pass objective.

Step 2: Build a clean three-light foundation

Start simple:

1. Key light - defines direction and primary form read
2. Fill light - lifts shadow regions without flattening forms
3. Rim or accent - separates silhouettes from background

Use large broad values first. Small dramatic accents come later.

Pro tip: If the key direction is unclear in grayscale, your scene will not read well in gameplay motion.

Step 3: Exposure lock and value hierarchy check

Before style polish:

• Lock exposure behavior for consistency (avoid auto changes while testing)
• Check your shot in grayscale
• Ensure focal objects are clearly separated from supporting props

A quick value test catches most stylized lighting mistakes earlier than color tuning.

Step 4: Add color scripting, not random color noise

Pick one primary temperature relationship:

• Warm key + cool fill, or
• Cool key + warm fill

Then assign secondary accents only where they support focal hierarchy.

Keep a short note:

• Primary: warm amber key
• Secondary: cool blue fill
• Accent: subtle magenta emissive near hero landmark

This note helps maintain consistency in Lesson 13 when matching in-engine post effects.

Step 5: Readability pass at gameplay distance

From your intended gameplay camera:

1. Confirm route edges are visible
2. Confirm interactable zones are not lost in shadow
3. Confirm set dressing does not overpower mission landmarks

If visibility fails, adjust contrast and placement before adding extra atmosphere effects.

Mini Task

Produce two screenshots of the same scene:

• Shot A: neutral working light
• Shot B: final stylized pass

Add a 3-bullet note:

1. What changed in key direction or ratio
2. What changed in focal readability
3. What color script rule you applied

Troubleshooting

• Scene looks muddy -> fill is too strong or color temperatures are too similar. Reduce fill intensity and re-separate warm/cool.
• Focal point disappears -> high-contrast accents are scattered; remove competing highlights near secondary props.
• Looks great in stills, bad in motion -> lighting only tuned for one camera. Re-test at gameplay camera height and movement speed.

FAQ

Should stylized scenes always use strong rim lights?
No. Use rim only when it improves silhouette separation. Forced rims can look artificial in dense scenes.

Do I need physically accurate lighting for stylized art?
Not strictly. Prioritize consistent readability and intentional mood over strict realism.

Recap

• You built a controlled key-fill-rim setup
• You validated value hierarchy and exposure stability
• You documented color script choices for later engine parity work
