Three.js: RENDER WARNING in two examples on Windows Chrome

[takahirox]

Description of the problem

I see RENDER WARNING in the two examples on my Windows + Chrome.

[.Offscreen-For-WebGL-000002652FEC91C0]RENDER WARNING: Render count or primcount is 0.

https://threejs.org/examples/webgl_octree.html
https://threejs.org/examples/webgl_materials_cubemap_dynamic.html

But I don't see on FireFox nightly. It could be (Windows) Chrome specific issue?

Possible duplicate of #8395 ?

It occurred in PlayCanvas as well back in 2016: https://github.com/playcanvas/fonts/issues/5

Apparently the fix back then was to ensure that the renderer isn't drawing anything if the draw count is 0.

I also see the warnings with Chrome on macOS (10.13.6).

webgl_octree should be okay now.

And the other one, too. There was some bad variable scoping in both examples which leads to undefined geometries/materials when creating meshes.
