Sandbox drag and drop: getting list of meshes based on total vertices

Questions

Good Afternoon all!

I was looking at this playground I found, showing a small version of the drag and drop files capability of the babylonjs sandbox.

So my question is this: How can I get an array of meshes from the file that was dragged and dropped and loaded into the playground based on a mesh’s total vertices? When loading files with the AssetsManager, I would rely on taskmanager, like so:

var assetsManager = new BABYLON.AssetsManager(scene);
meshTask = assetsManager.addMeshTask("mtask", "", modelpath, modelname + ".obj");
assetsManager.load();

meshTask.onSuccess = function (task) {
    let ms = task.loadedMeshes.filter(function (mesh) {
        return mesh.geometry._totalVertices > 0;    // this line fails
    });
    meshes = ms;
});

How do I get the meshes? I tried using
currentScene.meshes(x).geometry._totalVertices
but I error out.

Thanks for the assistance!

currentScene.meshes should contain all the meshes in the scene, it is possible that currentScene.meshes[0].geometry is undefined if the mesh is an empty node (eg. containing child meshes), try printing out the geometry to the console of each mesh to see which ones exist.

They’re there. I’m grabbing the wrong node. The model I’m using now is different from others I used from the same person. My mistake, I made an assumption. Thank you for helping me see the way!
