Set v-ray gi paths 

Set V-Ray GI Paths is a simple tool for quickly setting both Irradiance Map and Light Cache auto save and from file paths. When you are submitting jobs to be rendered this is one of those tedious things that you need to do which lends itself to human error as it is very easy to point a path to the wrong location (we have all done it)…

It has a very simple interface, basically you set the path where you would like the GI passes to be saved, type in a name and hit the button. This will set the paths for light cache and Irradiance maps. I have also added some quick options for swapping the modes of GI passes.
