BJS - [16:41:59]: Unable to load from …/…/common/res/3dModel/babylon/Dude/Dude.babylon: Error in onSuccess callback: TypeError: BABYLON.BoundingInfoHelper is not a constructor
I believe this is not Playground error.
Here is the example with Dude.babylon file - https://playground.babylonjs.com/#BCNJD4#57
Check your setup and your imports.
I moved your question from Bugs to Questions category.
Thank you
