Which lighting setup uses three light sources — key, fill, and back — to create a balanced, professional look for product renders?
Answer: Three-point lighting
Three-point lighting uses a key light (main), fill light (shadows), and back/rim light (separation) to create professional product renders.
What does HDRI stand for in the context of 3D product rendering?
Answer: High Dynamic Range Image
HDRI stands for High Dynamic Range Image, which captures a wide range of luminance data used to provide realistic environment lighting.
In 3D product animation, what is the purpose of a rim light?
Answer: To separate the product from the background by lighting its edges
A rim light is positioned behind the product to create a bright outline that visually separates it from the background.
Which render engine is commonly used in Blender for physically based product rendering?
Answer: Cycles
Cycles is Blender's built-in path-tracing render engine that supports physically based shading and lighting for product visualization.
What is global illumination (GI) in 3D product rendering?
Answer: A technique that simulates indirect light bouncing between surfaces
Global illumination simulates the way light bounces off surfaces and indirectly illuminates other parts of the scene for realistic results.
What is the primary advantage of using area lights over point lights for product animation in a US commercial studio workflow?
Answer: Area lights produce softer, more realistic shadows
Area lights emit light from a surface rather than a single point, producing soft graduated shadows that better simulate real-world studio light panels.
