Hi Roy. I have looked into this, and it would certainly be a great addition to the plugin, however I don't think it is something that will happen in the near future.
Hi Paul! It’s so difficult to do this implementation? Many users of Rhino using Grasshopper too (and this will grown up in the future) and the Vray feature is very powerful. I’m using both Octane and Vray (Vray only because of this). This is the link of my Blog where I show the use of Grasshopper and Vray for real time rendering: https://roads2022.com/blog-avenue
From looking at the documentation, I think this would be a huge amount of work. I doubt much of the current plugin code would work with the Grasshopper SDK.
