well, subject makes sense, right? hehe
the vray installed works fantastically for max, but not quite so for viz. We have to browse to our paths and work some magic on the DR files, add a vrayspawner.ini, and all that jazz.
So is there any you can show a lowly VIZ brother some love? 
Perhaps a “Which software are you using - VIZ or MAX?” radio button that will then take care of all these things for us…please?
