guys, I've been using sIBL GUI for months,the importer add-on for blender worked perfect with 2.77a ,
but does't really work in 2.78 RC, basically blennder itself will close right after I hit the 'Export button' in the sIBL GUI
sometimes it will work,but most cases it is just like get triggered and close.
so I wonder if any of you guys encountered same problem or it is just on my machine. and any chance solve the problem?
