Hello,
We expect to have a V-Ray 3.6 build for Rhino 6 released a week or two after the R6 commercial release and its public announcement (which according to our understanding hasn’t happened yet).
The v3.6 update is free for all existing v3.4 users.
The V-Ray 3 for Rhino licenses will apply to both builds for Rhino 5 and Rhino 6. As usual, it will be possible to run multiple instances of V-Ray for Rhino on a single computer (engaged licenses are counter per machine).
Kind regards,
Peter Chaushev
