About the warning "Please add an Enable WithThreeJS object to a scene."

⚠️ When using the WithThreeJS extension in GDevelop 5.3 or higher, you may receive a warning like this without seeing 3D.

This warning appears because GDevelop is not prepared to display 3D.

Simply adding an "Enable WithThreeJS" object to any scene will solve this problem.

Just add the "Enable WithThreeJS" object to one scene and all scenes are ready to display 3D. Also, the "Enable WithThreeJS" object works just by adding it to the list of scene objects. There is no need to place it in the scene.

Why doesn't this warning appear on my project?

This is because if GDevelop's 3D Box object or 3D Model object is used in the project, it will be ready to display 3D without using the "Enable WithThreeJS" object.

I am using WithThreeJS version lower than 1.0.2.

Please add a 3D box to Scene objects (no need to place it in the scene). That alone will solve this issue.

I'm using WithThreeJS v1.0.2 with GDevelop v5.2. Can I update to GDevelop v5.3 without any problems?

No, please re-import WithThreeJS v1.0.2 or above again after updating to GDevelop v5.3.
