Download link and install information
-Fixed path with spaces in windows.
-Fixed alert messages.
Ive implemented some of BrikBot suggestion, Some of them are:
-Linux and mac users doesnt have to change the script to get it working.
-The addon uses its own folder. So you can copy the folder to other machine and will work the same.
-Minor changes to material preview.
Please read the installation process at the web site.
