Read the first 6 3D Layers and Camera Tools flashcards as text
Which After Effects renderer supports extruded 3D text and shape layers with real geometry?
Answer: Cinema 4D Renderer
The Cinema 4D Renderer (included with After Effects) enables true 3D geometry for extruded text, shapes, and environment layers.
What does the 'Zoom' property on an After Effects camera represent?
Answer: The focal length equivalent that determines the angle of view and perspective compression
Zoom (measured in pixels) is equivalent to focal length — higher Zoom values narrow the field of view and increase perspective compression.
What is the 'Enable Depth of Field' checkbox in the camera's settings linked to?
Answer: The Focus Distance, Aperture, and Blur Level parameters that control the out-of-focus blur amount
Enabling Depth of Field activates post-process blur based on the camera's aperture and focus distance, simulating optical lens defocus.
How does parenting a camera to a Null Object benefit 3D camera animation in After Effects?
Answer: It allows moving and rotating the camera via the null while preserving separate local camera adjustments
Parenting the camera to a null lets you animate the entire rig (null) separately from local camera tilts and rolls, enabling crane-like or handheld camera setups.
What does the 'Acceptance Angle' of a Spot light in After Effects control?
Answer: The width of the cone of light emitted, determining how wide the lit area spreads
The Cone Angle property of a Spot light controls how wide or narrow the illumination cone is, affecting the spread of light in the scene.
What happens to a 3D layer's rendering order in After Effects when two 3D layers intersect in Z-space?
Answer: After Effects sorts them by Z-depth per-frame, but may produce artifacts at intersection points with the Classic renderer
The Classic 3D renderer sorts layers by their Z-position center, causing visual artifacts when layers truly intersect; Cinema 4D renderer handles intersection correctly.
