This Asobo gltf addon and Blender 3.4 isn’t working for me either. Placing the folder as instructed by Asobo. I also read in their ReadMe file that you can execute the compressed file via the install Blender addon button, but that didn’t work either.
The plugin is being installed correctly however, as shown in the image below, the import option is not appearing. It’s my guess the “complete” installation process is not being executed and the users who got the addon working just got lucky with the install, or perhaps are using older Blender versions, conflicts, etc.
Kellytoons, I had issues importing the Cessna 172 as well but then I realised I was still using bestdani v0.1. After updating to v0.4, I can import a lot more planes without trouble, including the C172.
