Another newbie question,
Is there a built-in way to spit out the number of faces that a mesh has within a scene? If so, how do I use it?
I attempted to return a number from getTotalVertices() from the human figure in this playground, but it returned zero instead. I must need to access a nested child mesh somehow:

What I suspect is that this mesh is a combo of low poly model and smooth shading to make it appear like a more complex geometry, but I want to be able to study polycount of a given mesh regardless.
You are right, the Dude is composed a several child meshes:
On a specific mesh, you can use mesh.getTotalVertices() and mesh.getTotalIndices()
Thank you as always for your swift reply @Deltakosh 
I logged a rather high number when I ran this. It reflects a single sub mesh or the entire body of “dude”?
console.log(dude.getChildMeshes()[0].getTotalIndices()) // Returns 21690
This playground runs smoothly even though I expected to see some slow down on mobile, so I’m attempting to use it as a test case for poly count in a scene.
It is the number of indices per mesh. Number of faces or triangles = indices / 3
