- Added interaction helpers for cutout region validation and shape menu interaction. - Created main operator for converting image regions into cutout shapes, including AI artifact generation. - Introduced object creation logic for cutout shapes, handling depth and normal textures. - Defined cutout shape identifiers and node groups for various shape types. - Implemented depth texture writing and prediction artifact generation for MoGe-2. - Developed server jobs for generating cutout artifacts, depth planes, and refining image regions. - Added region refinement logic to enhance gesture masks using BEN2.
