Question 1

In a 3D product animation pipeline, what is the main purpose of a 'render farm'?

Accepted Answer

Distributing rendering tasks across multiple computers to reduce render time

Answer

A render farm parallelizes render jobs across many machines, dramatically reducing the time needed to produce high-quality animation frames.

Question 2

Which compositing technique is used in post-production to isolate and adjust only the 3D product object separate from its background?

Accepted Answer

Render passes / AOVs (Arbitrary Output Variables)

Answer

Render passes (AOVs) output separate image layers like diffuse, specular, and shadow, allowing fine-tuned compositing control in post.

Question 3

When building a product animation for social media ads, what aspect ratio is optimal for Instagram Stories and TikTok?

Accepted Answer

9:16

Answer

9:16 vertical format fills the full screen of mobile-first platforms like Instagram Stories and TikTok, maximizing viewer engagement.

Question 4

In 3D product animation, what does 'IOR' (Index of Refraction) control in a material shader?

Accepted Answer

How much light bends when passing through a transparent material

Answer

IOR determines how strongly light rays bend at the boundary of a transparent material, affecting the look of glass, water, and gems.

Question 5

What is the typical frame rate used for high-quality 3D product animations intended for commercial broadcast in the US?

Accepted Answer

30 fps

Answer

30 fps (29.97 fps NTSC) is the standard broadcast frame rate in the US, ensuring compatibility with television and streaming platforms.
