- Added a new proposal for boundary smoothing in the weight cutout process, differentiating between Split edges and Outline smoothing requirements. - Introduced a new capability `cutout-boundary-smoothing` to control smoothing strength and default values. - Updated specifications to define the behavior of boundary-specific smoothing strength and default settings. - Created tasks to verify the implementation of boundary behavior and asset updates. - Developed comprehensive tests for depth symmetry and normal scaling to ensure expected behavior and performance. - Introduced new attributes for normal mapping to facilitate persistent face attributes sharing between depth symmetry and image materials. - Built a new node group for O Image Depth Symmetry, integrating the new smoothing capabilities and ensuring compatibility with existing workflows.
