Vray Not loading in Rhino 8

So I have updated to Rhino 8 (trial at moment) and the Latest Vray (which is apparently compatible ) whilst Vray still works on Rhino 7 when i switch renderer in Rhino 8 it just says current plugin set to Rhino Render - its driving me nuts as our whole workflow is for Vray

Hello, Thomas,
Apologies for the confusion!
V-Ray 6.10.03 only supports the beta version of Rhino 8.
We have finalized and hope to release soon a V-Ray update that will bring support for the official Rhino 8 release version.

Kind regards,
Peter Chaushev

V-Ray 6 for Rhino, Update 2 is now released, available here:
https://download.chaos.com/?platform=51&product=47

Among many new additions it also brings Rhino 8 support.

hi This still doesn’t seem to work - downloaded newest vray (Dec 8 version) this morning still cannot set to renderer - for my work flow this really nullifies being able to use Rhino 8 !

Can you please share the exact version of Rhino 8 you use (Rhino menu Help > About)?
Additionally, if you open the Plugin Manager (type in _PluginManager) what is the state of V-Ray in that list?
Lastly, when attempting to set V-Ray as the current renderer what exactly is printed in the Rhino command panel?

Hi I am using Rhino 8.2.23346, and it says its up to date, I have downloaded the latest vray which has an option for Rhino 8 Version 6.20.01 - I go to select the renderer but as soon as I close the properties tab the command line says Rhino Render selected.

I’m having this exact same issue.

@Thomas_Boundary @CallmeCatbread
Could you try:
Run _PluginManager
In that dialog click the Install… button
browse to:
C:\Program Files\Chaos Group\V-Ray\V-Ray for Rhinoceros\V8
double click VRayForRhino.rhp

I was having issues a while back getting to run Vray in Rhino 8 and that solved it for me.

Hello Peter,
Is there a way to use V-Ray 5 with Rhino 8 or is V-Ray 6 needed?

Hello, Bjorn,
V-Ray 5 does not work with Rhino 8. Only V-Ray 6 runs on Rhino 8.
The latest V-Ray update (v6.20.02 or later) is recommended as it contains a number of improvements to its Rhino 8 support.

So i have just done the Vray update and here again! says plugin is loaded but just cannot be set as the plugin

Rhino 8 has no _PluginManager command.

Same issues here. VRay can run, but there are no Vray toolbars or options to enable them from the toolbar listing.

Hi @jason.cross.ima Rhino 8 does have that command. If it doesn’t run something is wrong at your end. In that case run SystemInfo in Rhino and post back the results. For installation issues of VRay it’s best to contact Chaos directly.

I PI have also published a post on the topic regarding the problem and maybe my way of getting the plugin to work will help you.

Rhino 8 Vray 6 loading Problem - McNeel Forum

I hope it’s understandable, English is not my native language.

Problem fixed for me by drag and dropping the VrayforRhino.rhp file into rhino.

from Program Files\Chaos Group\V-Ray\V-Ray for Rhinoceros\V8

I’m also experiencing an issue with the V-Ray toolbars. In the toolbars panel, V-Ray appears and can be checked, and the toolbar itself shows up. However, all the icons are crossed out and non-functional. Additionally, I have to reinstall the .rhp file every time I start Rhino, as the plugin gets blocked upon launching Rhino 8.

I’ve already downloaded and installed the latest versions of both Rhino 8 (8.14) and V-Ray (6.2006), restarted my computer, and tried troubleshooting. Unfortunately, without success.

I understand you may not be the right person to address this issue, and it may rather be something the Chaos team needs to resolve. However, I’m sharing it here in case someone from their team is reading or if anyone else has encountered and fixed a similar problem. Any advice or solutions would be greatly appreciated!

Is there a VRay related xml file? If so, you can safely delete that file. (do this while Rhino is NOT running)
This should bring back the Vray toolbars back in their shipping state.

What do you have set here in plugin manager, if the Enabled is not checked it means it gets blocked when loading:

Thank you for the swift reply, Gijs. I located the (hidden) settings folder and there are “scheme_default” xml’s but these unfortunately dont seem to be vray-related.
I did find a Rhino toolbars file in “C:\Program Files\Chaos Group\V-Ray\V-Ray for Rhinoceros\V8”, dropped ot to the canvas, hoping this would help, but the issue still remains the same →


.

@robert6 To me it looks like you have drag-and-dropped the Vray toolbar to the default toolbar.
I’d just drag that toolbar out and close it, and reopen the toolbars from the VRay RUI file:

That’s it! You’re the best:) Thanks.
