Which render pass is most useful for isolating a product's reflective highlights during compositing?
Answer: Specular pass
The specular pass captures only the glossy reflection highlights, allowing compositors to adjust sheen intensity independently.
In 3D product animation, what is the primary purpose of using a 'turntable' animation?
Answer: To show all sides of the product by rotating it 360°
A turntable rotates the product a full 360° so viewers can inspect every angle without camera movement.
What does the term 'UV unwrapping' refer to in 3D product animation?
Answer: Flattening a 3D mesh into a 2D layout for texture mapping
UV unwrapping converts a 3D surface into a flat 2D map so textures can be painted or applied accurately.
Which technique is commonly used to make a product label appear painted directly onto a curved surface rather than floating above it?
Answer: Decal projection
Decal projection wraps a texture onto the underlying geometry so it conforms tightly to the surface curvature.
In a physically based rendering (PBR) workflow, what does the 'metallic' parameter control?
Answer: How much the surface reflects light like a metal versus a dielectric
The metallic value (0–1) determines whether the material uses metal-like direct reflections or dielectric diffuse/specular separation.
Which camera setting most directly controls depth of field blur in a 3D product render?
Answer: Aperture (f-stop)
A lower f-stop (wider aperture) produces more background blur, mimicking the shallow depth of field used in product photography.
What is the function of a 'holdout' shader in 3D compositing for product animation?
Answer: Makes a surface invisible but retains its shadow and reflection contributions
A holdout shader renders the object as a transparent cutout while preserving its interaction effects like shadows, enabling seamless compositing over live footage.
