- Implemented `image_plane.py` to build the Image Plane Geometry Nodes group with customizable parameters for geometry, subdivide, and thickness. - Created `image_plane_validation.py` to validate the functionality of the image plane, ensuring correct geometry generation and material assignment. - Developed `material_layers.py` to construct shader node groups for image materials, including depth and normal handling. - Authored `plane_layouts.py` to define node arrangements for image geometry assets. - Introduced `shadeless.py` to create a shadeless shader node group that displays color without scene lighting while preserving shadows and reflections.
