- Replace Delete Geometry with Separate Geometry in O Image Depth Panorama to manage low and high mask areas independently. - Adjust depth processing to ensure low mask regions are displaced to Dome Radius while high mask regions follow existing depth rules. - Update tests to validate new behavior, ensuring outputs align with expected results for both mask states. - Enhance material handling by introducing emission strength in the shadeless group.
