V-Ray 7.20 plugin fails to load in Rhino 9 WIP (9.0.25308)


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 build

The same plugin still loads and runs fine in Rhino 8 (stable).

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(), etc.. but when I override PlugInType() Rhino never calls my implementation. So it is some subtle C++ quirk like ctor().call()instead of instance->call()

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