Textures invisible through reflective material

For the record: dynamic cube-mapped reflections were implemented in version 15.05

That's a pretty neat feature, I've read about it in the release notes.
It's been a while since I last played with Blend4Web, gotta get back to it, and this looks like a great excuse to finally finish this model.

Could you tell me the workflow for creating cube-mapped reflections please? I've looked around on the forum for a long time and can't seem to find out how to do it..
I can only find the demo
link

Thanks
