What is a rigid body simulation used for in 3D product animation?
Answer: Simulating physically accurate collisions and dynamics for solid product objects that don't deform
Rigid body simulations calculate physically accurate collision, gravity, and momentum for solid objects — such as a product falling onto a surface or multiple units tumbling.
What does 'baking animation' mean in a product animation production pipeline?
Answer: Converting procedural or simulated animation into explicit keyframe data for portability and rendering stability
Baking animation converts dynamic simulation results or procedural motion into fixed keyframe data, ensuring consistent playback and enabling export to other software.
What is the NLA editor (Non-Linear Animation editor) used for in product animation?
Answer: Blending, layering, and reusing animation clips in a non-destructive track-based system
The NLA editor lets animators create reusable animation strips that can be blended, scaled, looped, and layered — ideal for building product animation sequences from modular motion clips.
What is motion path visualization used for during 3D product animation?
Answer: Displaying the trajectory curve of an animated object to review and adjust the path's shape and timing
Motion path display shows the curved arc an animated object follows in 3D space, allowing animators to spot and correct unnatural kinks or incorrect arc shapes.
What is the purpose of 'weight painting' in product animation rigging?
Answer: Defining how strongly each bone in a rig influences specific vertices of the product mesh
Weight painting assigns influence values (0–1) from rig bones to mesh vertices, controlling how smoothly or rigidly areas of the product deform when bones move.
In product animation production, what is the role of a 'null object' or 'empty' object in a rig hierarchy?
Answer: A non-rendering control object used as a pivot, parent, or reference point in the rig hierarchy
Null/empty objects have no visible geometry but serve as parent nodes, pivot points, or control handles in the rig — keeping the hierarchy clean without adding render overhead.
