Thanks for your incradible work @blanchg!

Here's an interior test i'v just render using corona exporter.

One problem i'v faced: can't use opacity maps. It's produce an error:

Traceback (most recent call last):
  File "C:\Program Files\Blender Foundation\Blender\2.78\scripts\addons\render_corona\engine.py", line 353, in render
    render_start( self, scene)

    xml_tone = SubElement(target, 'map')
TypeError: must be xml.etree.ElementTree.Element, not str

What am i doing wrong?

EDIT:
When i create a material via the node editor, everything OK. the problem is just when i'm trying to use opacity map via the properties panel.
