Problem activate Vray render

Im just ad Vray to my Rhino,
Installing is finished with no problem…
When im running rhino, toolbar is avaible, but in property (render) i need to choose (rhino render or Vray render, i see both choice…) but i can select Vray render,
In property, Vray is Activate
on commande line:
DéfinirModuleRenduActuelE8CFE179-B60C-411A-8416-62A893334519 (in frecnh…)

(sorry for my medium english, hope you understand my problem…)

Thx per advance for your help :slight_smile:


In the Render pull-down menu, there is a Current Render sub-menu.
Is Vray selected in that sub-menu?


I have the exact same problem in 2020, I just installed an evaluation version of V-ray for Rhino 6.

I checked the Current render sub-menu, Rhino Render is selected but when I select V-ray, it goes back to Rhino Render displaying this message:
Unknown command: DefineCurrentRenderedModuleE8CFE179-B60C-411A-8416-62A893334519

Thank you for your response
