PanoCamAdder Light is an add-on that assists in creating 3D models from equirectangular panoramas. It provides a specialized camera and material setup that functions as a 360-degree viewer and a visual reference for the modeling process. Users can add hotspot placeholders with the correct ratio, size, scale, and rotation directly into the scene. The included viewer tool allows for quick activation of panoramic cameras and seamless switching between different panorama materials.
