Broken example? [Box Projected cubemap environment mapping]

Hi there!
I’m trying to achieve a believable fake reflection for a room size environment… so i was wondering if Verge3D could implement the BPCEM, and after some web searches i’ve found the threejs implementation and the example

For reference:
New version:
https://threejs.org/examples/?q=envm#webgl_materials_envmaps_parallax
Old version:
https://rawcdn.githack.com/mrdoob/three.js/r107/examples/webgl_materials_envmaps_parallax.html

So looking for the same name (Box Projected cubemap environment mapping) into the Verge3D it’s there!
but it seems to be somehow broken

Hoping to see it up and running soon and to understand how to implement it..
Cheers!
