Technical glTF animation file demonstrating the KHR_node_visibility extension applied to a punctual light for real-time toggling. This technical asset serves as a functional reference for implementing light visibility within the glTF format. It specifically demonstrates the application of the KHR_node_visibility extension to a punctual light source, controlled via the KHR_animation_pointer extension. The file is structured to show a clean, repeatable animation loop where the light source toggles between visible and hidden states. It provides a precise implementation example for developers and technical artists working with real-time engines, ensuring that light state changes are correctly interpreted and rendered according to the current open-standard specifications for glTF.

The download is a single file with the model in GLB format.

Users should import this file into a glTF-compatible viewer or real-time engine to inspect the node hierarchy and animation data. It is intended for use as a reference implementation for developers building custom shaders or exporters. The animation track can be examined in the source software to understand how the visibility property is keyed and mapped to the animation pointer, facilitating the integration of similar toggling behaviours into complex 3D scenes and interactive digital experiences.

This file is suitable for developers and technical artists working on interactive web-based 3D projects, virtual reality environments, and real-time configurators. It provides a reliable baseline for testing light state animations in various glTF loaders and rendering engines. Professionals can reference this asset when troubleshooting light flickering, visibility issues, or animation sync problems in complex interactive models. It is particularly useful for those developing standardised pipelines for web-based product displays where dynamic light control is required for enhanced realism and performance.
