When animating a spray bottle pump in 3D, which rigging approach best handles the pressing and releasing motion?
Answer: Driven keys or constraints tied to a single control
Driven keys link the pump head's translation to a single control so pressing one slider animates all dependent parts automatically.
In 3D product animation, what is 'chromatic aberration' used for when applied in post-production?
Answer: Adding a lens imperfection effect to make the render look more photographic
Chromatic aberration subtly splits color channels at the frame edges, mimicking real camera lens behavior for a more organic look.
Which lighting technique uses a large rectangular light source positioned to create a long, elegant reflection on a product like a perfume bottle?
Answer: Strip/softbox lighting
Narrow strip lights produce the characteristic elongated specular highlight seen on glass and plastic beauty products.
What does 'caustics' refer to in 3D product rendering?
Answer: Bright light patterns formed when light refracts through transparent objects
Caustics are the concentrated light patterns projected onto surrounding surfaces when rays pass through glass, water, or other refractive materials.
In product animation, what is the advantage of rendering in EXR (OpenEXR) format over standard JPEG?
Answer: EXR stores 32-bit HDR data, preserving full highlight and shadow detail for compositing
OpenEXR's high dynamic range data gives compositors flexibility to recover blown highlights or crushed shadows in post without quality loss.
Which 3D software node is typically used to mix two different materials based on a mask texture in a product shader?
Answer: Mix Shader / Blend Material node
A Mix Shader blends two materials using a grayscale mask, enabling effects like a glossy label over a matte plastic body.
When creating a product animation for social media (e.g., Instagram), what aspect ratio is most commonly targeted for Stories and Reels?
Answer: 9:16
9:16 is the vertical full-screen format native to Instagram Stories and Reels, maximizing screen real estate on mobile devices.
