Hi,
I'm trying to make a level in Blender with the blender2crystal exporter at
https://crystal.svn.sourceforge.net/svnroot/crystal/CS/trunk/scripts/blender/ ; I've read the documentation at
http://www.crystalspace3d.org/docs/online/manual/Portal-Engine.html#0 and tried to make a simple area following the "portaltut" example file, but still I can't get the portals to work

I'm attaching the world file and also the original .blend file, can someone help me making the thing work?
Thanks
Andrea
