Version 1.2 – Blender 2.8 Update

ProLighting Studio 1.2 now supports Blender 2.8. Please note, it may have a small system message on Blender 2.79 saying “the addon was made for a newer version of blender”, but should still function, if you run into any issues please revert to version 1.1 for Blender 2.79.
We do not recommend using version 1.2 on older versions of Blender (eg 2.75 or earlier) as it may not function correctly.
