I’ve been very short on time lately and haven’t had much of a chance to look into fixing the 3Delight/Blender addon to work with recent Blender Python API changes. Jeff Doyle (nfz) however, has generously gone through the code and updated it to work with a current Blender SVN version (as of today, r35311). I haven’t been able to spend a huge amount of time testing it, but on a brief inspection it seems to be working well.
Since you’ve been waiting for a new working version, I’ll release Jeff’s changes now, and hopefully spend a bit more time soon with some other fixes.
