3D Product Animation 3D Product Animation MCQ 2

Question 1

Which render pass is most useful for isolating a product's reflective highlights during compositing?

Accepted Answer

Specular pass

Answer

The specular pass captures only the glossy reflection highlights, allowing compositors to adjust sheen intensity independently.

Question 2

In 3D product animation, what is the primary purpose of using a 'turntable' animation?

Accepted Answer

To show all sides of the product by rotating it 360°

Answer

A turntable rotates the product a full 360° so viewers can inspect every angle without camera movement.

Question 3

What does the term 'UV unwrapping' refer to in 3D product animation?

Accepted Answer

Flattening a 3D mesh into a 2D layout for texture mapping

Answer

UV unwrapping converts a 3D surface into a flat 2D map so textures can be painted or applied accurately.

Question 4

Which technique is commonly used to make a product label appear painted directly onto a curved surface rather than floating above it?

Accepted Answer

Decal projection

Answer

Decal projection wraps a texture onto the underlying geometry so it conforms tightly to the surface curvature.

Question 5

In a physically based rendering (PBR) workflow, what does the 'metallic' parameter control?

Accepted Answer

How much the surface reflects light like a metal versus a dielectric

Answer

The metallic value (0–1) determines whether the material uses metal-like direct reflections or dielectric diffuse/specular separation.
