[Screenshot 2025-11-05 084652] [Screenshot 2025-11-05 090043] Hi @Nikolay @brian , After today’s Rhino 9 WIP update (9.0.25308), the V-Ray 7.20 plugin no longer loads. Has there been a recent SDK change, or is this a bug introduced in the current WIP build? For reference: Rhino 9 WIP — today’s …

It could be pointing to the wrong rhp If you go to _PluginManager, then right click Vray and click Properties, what does it point to in File Name?

WIP builds are experimental, as you know, and I can repeat the issue here with the latest installer. RH-90313 Vray for Rhino no longer loads

It is certainly not V-Ray. The PluginType() that is quoted is not overridden by V-Ray since we inherit from CRhinoRenderPlugIn which provides implementation of PluginType(). I guess it returns plugin_type::render_plugin Anyway with the debugger I get some of the main functions called - PlugnInName…

I’d like to report the similar issue is happening with the paneling tools plugin. exact same error pops-up

I have to same problem loading V-Ray in the latest WIP. [Screenshot 2025-11-11 103922]

Hi all - A Rhino WIP version with a fix for this issue should be released in a few hours from now. -wim

Hi, I can confirm that Vray and other plugins like xnurbs, now load without problems in Work In Progress (9.0.25315.12305, 2025-11-11) Thanks
