  1. During a model review, you notice the pivot point is far from the mesh. Why does this matter for production?

    Answer: Incorrect pivot causes wrong rotation and scale behavior in engines and animation rigs

    The pivot (origin) defines the center of rotation and scaling, so a misplaced pivot causes objects to rotate or scale from the wrong point.

  2. What is the standard method for verifying a hard-surface model's surface continuity before delivery?

    Answer: Enable matcap or reflective shader to reveal bumps and dips in the surface

    Matcap or reflective shaders highlight surface imperfections that are invisible under flat diffuse lighting.

  3. A model exported from ZBrush has inverted normals on import into Maya. What is the fastest fix?

    Answer: Reverse normals or flip faces in the target application

    Reversing or flipping normals in Maya corrects the orientation without altering the underlying geometry.

  4. What does a 'manifold' mesh guarantee in 3D modeling?

    Answer: Every edge is shared by exactly two faces

    Manifold geometry requires each edge to be shared by exactly two faces, ensuring the mesh has no holes or impossible intersections.

  5. Which QA check is critical before baking a high-poly mesh onto a low-poly mesh?

    Answer: Ensuring the low-poly cage fully encloses the high-poly mesh without gaps

    If the cage doesn't fully enclose the high-poly, the baking rays will miss geometry and produce errors in the normal map.

  6. What does checking 'object naming conventions' achieve in a QA pipeline?

    Answer: Ensures assets are identifiable, scriptable, and follow pipeline standards

    Consistent naming allows automated scripts, engine importers, and team members to locate and process assets reliably.

  7. What is 'polycount budget' in a production context?

    Answer: The maximum number of polygons an asset is allowed to use as defined by the project's technical spec

    A polycount budget ensures all assets perform within the hardware constraints set by the platform or scene complexity requirements.
