Hi
The RPM for 2020 was compatible with 2021 as 3dsmax 2021 doesn't require a plugin recompile, but the installer has been updated to indicate this:
http://www.rpmanager.com/installers/RPM ... p_7.07.exe
Also improved VRay 5 UI - it was defaulting to a much older layout file than even VRay 4, and was a bit of a mess.
cheers,
