I don’t know about the diff between inspector v1 and v2 for bounding info. But you can access a mesh variable via the inspector and access it on the console. Go to the mesh you want or scene, go to properties and click on the copy button on any of it’s properties. Then go to the console, paste : You will have something like:
globalThis.debugNode.isVisible = true; // (debugNode as BABYLON.Mesh)
