What do I do when I use the Babylon Editor export and I pop up this prompt？
Adding the amazing daddy of the editor @julien-moreau
Hey @hugoZeng !
The editor you are using (v3) is old and I suggest that you use the v4 instead. The version 4 provides more useful/powerful tools to help creating scenes.
You can download it here: BabylonJS Editor v4.0.0 beta · BabylonJS/Editor Wiki · GitHub
And read the WIP documentation here: Editor/doc.md at release/4.0.0 · BabylonJS/Editor · GitHub
