Normal Mapping

Term from Video Game Development industry explained for recruiters

Normal mapping is a technique used in video game art to make simple 3D objects look more detailed without making the game slower. Think of it like putting a very detailed sticker on a simple surface to make it look more realistic - like making a flat wall appear to have brick texture and depth. Artists use this method to add realistic details like scratches, bumps, or texture to game objects while keeping the game running smoothly. This is essential in modern game development because it helps create visually impressive games that still perform well on different devices.

Example Interview Questions

Senior Level Questions

Q: How would you optimize normal maps for a mobile game with limited memory?

Expected Answer: A senior artist should discuss techniques like proper resolution sizing, compression methods, and smart reuse of normal maps across different assets while maintaining visual quality.

Q: How do you manage normal map creation for a large environment with varying detail requirements?

Expected Answer: They should explain prioritizing detail levels based on player view distance, efficient tiling techniques, and managing texture memory budget while maintaining consistent quality.

Mid Level Questions

Q: What's your process for creating normal maps for organic versus hard surface objects?

Expected Answer: Should explain different approaches for natural objects like rocks or skin versus mechanical objects like weapons or vehicles, and common tools used for each.

Q: How do you ensure normal maps work well across different lighting conditions?

Expected Answer: Should discuss testing normal maps under various in-game lighting conditions and making adjustments to ensure details are visible but not overpowering.

Junior Level Questions

Q: What tools do you use to create normal maps?

Expected Answer: Should be able to name common software like Photoshop, Substance Painter, or ZBrush and explain basic normal map creation workflow.

Q: How do you test if a normal map is working correctly?

Expected Answer: Should explain basic testing methods like viewing the model in a game engine or 3D software and checking how details appear under different angles and lighting.
