Testing and validation typically extend 3D production timelines by requiring iterative checks and revisions to ensure models meet technical and quality standards.
Key factors contributing to timeline extensions include: - **Geometry validation**: Identifying mesh errors (e.g., non-manifold edges or overlapping polygons) that demand redesign to avoid rendering or printing failures. - **Texture/rendering checks**: Ensuring consistent color, lighting, or material application, often requiring shader adjustments or UV map rework. - **Functional testing**: For use cases like 3D printing or AR/VR, verifying structural integrity or interactive performance, which may necessitate design tweaks.
Minor issues cause short delays, but major errors (e.g., critical structural flaws) can significantly prolong timelines due to repeated rework cycles.
