I've been trying to install the Three.js exporter in Blender 2.76b on Ubuntu 14.04 and it's not showing up in the Addon's list in Blender.
I put the io_three folder in /usr/libs/Blender/scripts/Addons folder using Nautilus in gksudo mode and it's still not showing up when I open blender, any suggestions?
I even tried installing an older version of the addon as well and still no go. Do I need to install an older version of Blender to get it to work? I got it to work in Windows no problem.
