Environment map in the threejs editor, how to?

I am trying to set up an environment map using the threejs editor to achieve something like this:

I assumed it would only take a equirect image set as the background and then apply the environment image to the Env. Map in the material settings. But I do not see the map when I press Play.

Perhaps I have to have other maps enabled for it to work or there is a setting I am not aware of that needs to be turned on?

Thanks in advanced for the tips!!
