- Introduced color_image.py for preparing standalone color images for tests. - Added hdr_image.py to create HDR textures for testing. - Implemented test_image_depth_panorama.py to evaluate panorama topology, UVs, and depth discontinuities. - Created test_shadeless.py to validate the opacity and HDR color endpoints of the Shadeless group. - Developed moge3_export.py for exporting dynamic MoGe-3 backbone and ONNX graphs. - Added material.py to inherit material slots onto generated geometry. - Built image_depth_panorama.py to construct a quad panorama with depth separation and sampling.
