What is the purpose of 'light linking' in a 3D product animation scene?
Answer: Assigning specific lights to illuminate only selected objects
Light linking lets artists control which lights affect which objects, enabling selective illumination of a product without affecting the background.
Which rendering technique shoots multiple rays per pixel to reduce noise in soft shadows and global illumination?
Answer: Path tracing / Monte Carlo sampling
Path tracing uses Monte Carlo sampling — many rays per pixel — to approximate realistic light bounces, producing accurate soft shadows and global illumination.
For a luxury perfume bottle product animation, which material property setting would best achieve a glass look?
Answer: Low roughness, IOR ~1.5, high transmission
Glass is characterized by low roughness (smooth surface), an IOR around 1.5, and high transmission so light passes through the material.
What does 'camera mapping' (or camera projection) allow in product animation production?
Answer: Projecting a photograph onto 3D geometry to create realistic textures from reference images
Camera mapping projects a 2D photo onto 3D geometry from the camera's perspective, allowing photorealistic textures derived directly from reference photography.
In a 3D product animation workflow, what is a 'proxy object' used for?
Answer: A low-resolution stand-in used during animation to speed up viewport performance
Proxy objects are simplified, low-poly stand-ins that replace heavy geometry during the animation phase, making scene manipulation faster and more responsive.
Which color space should source textures be imported in when working in a linear workflow for product rendering?
Answer: sRGB (gamma-encoded)
Color textures (diffuse/albedo) should be tagged as sRGB so the renderer applies the correct gamma linearization before using them in light calculations.
What is the function of an 'ambient occlusion' bake in product visualization?
Answer: It pre-calculates soft shadowing in crevices and contact areas to add depth
Ambient occlusion baking pre-computes how much ambient light reaches each surface point, darkening crevices and contact areas to enhance perceived depth and realism.
