mostly max. THat Vray is in its beta stage and it seems like its been over a year since they release the beta. There is still a lot of setting missing and that Vray doesnt work as good for maya as it does for max seeing that its in its beta stage. Hmm i could be mistaken but last vray for maya i had was the beta and I mean A lot and really ALOT of settings were missing and it was crap so i never used it for maya. I use it for max because the one for max is just perfect but yea the one for maya needs a lot of help and i emailed them about it to see and they said they are still working on it to get it better but that was last year so I dont know if they actually came out with the real version or not
