This application project (HShglTFImporter / HShglTFExporter) has been officially transferred to The Khronos Group and released as a fully open-source project.

Following this transition, license sales on this website have been discontinued.
The latest versions of the importer and exporter plugins can be downloaded from the GitHub repository below:
https://github.com/KhronosGroup/glTF-3ds-Max-Plugin/releases

Important Installation Notes:

Manual Installation Required: Please note that an installer (.msi/.exe) is not provided. You will need to copy the plugin files directly into your 3ds Max installation directory (e.g., the plugins folder).

Plugin Name Conflict: The newly released plugins use different filenames than the previous version. To prevent system conflicts, please make sure to completely uninstall or remove the older HSglTF plugins before installing the new ones.

For Users with Active Licenses:
You may continue using your current version until your license expires. However, please note that no further updates will be provided for the legacy plugins. We highly recommend switching to the latest open-source version available at the GitHub link above (and remember to uninstall the old version first!).
