Unable to make vray render the current render in rhino 8

I can’t set the render engine to Vray it’s keep the render set as rhino render

You should change render engine in Rhino settings, and restart (Rhino).

Normally a restart should not be needed, if Vray is enabled and loaded.
Are you saying from the menu, Render > Current Renderer > clicking V-Ray for Rhino does not work?
If so, pls run _SystemInfo and post back the results

this is what I did, and it’s go back to rhino render every time

Mind that V-Ray 6.10.03 is compatible with Rhino 8 BETA, not with the official release. Rhino might check that and revert your change.

Just guessing, though

Nikolay Bakalov already mentioned, V-Ray 6.10.03 only supports the beta version of Rhino 8. I understand our download platform’s premature adjustment to the Rhino version numbering caused confusion. Apologies!

Minutes ago we released V-Ray 6.20.00 - it comes with Rhino 8 support and is available for download here:

Kind regards,
Peter Chaushev

I have installed Rhino 8 (final version) and Vray 6.10.03 and everything works normally, plug-in recognized and installed correctly (maybe because I also have version 7 of Rhino installed? I don’t know…).

This is logged here: RH-78745 Selected render engine in document properties > Render does not stick

I just Install it. it does not work yet
