[v3.1-alpha] Inspector fails to load after physics impostor is added to externally-loaded mesh

I’m fetching a low-poly tree model from an external .obj file via the AssetsManager and adding a cylinder physics impostor after it has finished loading. All of this is working fine. Here’s my tree: Next, I’m duplicating the tree and adding more because Bob Ross said they get lonely, but I digress.

Here’s the code:

var loader = new BABYLON.AssetsManager(scene);
var tree = loader.addMeshTask("happyTree", "", "meshes/", "tree.obj");
loader.load();
tree.onSuccess = function (task) {
  var treeMesh = BABYLON.Mesh.MergeMeshes(task.loadedMeshes);
  treeMesh.material = treeMaterial;

  var tree1 = treeMesh.clone();
  treeMesh.dispose();

  tree1.position = new BABYLON.Vector3(-20, 17, 10);
  tree1.physicsImpostor = new BABYLON.PhysicsImpostor(tree1, BABYLON.PhysicsImpostor.CylinderImpostor, { mass: 0, restitution: 8 }, scene);
  ...
}

If I comment out the line where I assign tree1.physicsImpostor, the inspector loads fine. As it stands, this is what I’m seeing in the JS console:

I’m pulling down the relevant JS files from preview.babylonjs.com just to make sure I have the latest and greatest. Seen on Chrome v60.0.3112.101 on Windows 10.

This is the first issue I’ve filed in this repo, so please let me know if I’ve forgotten anything!

And since localCompare is used during string-comparison, maybe try giving tree1 a name

Nailed it! That fixed the issue.

Thanks! 😄
