Maybe this is something for Rhino 5 and Vray for Rhino 2…but is it possible within the Render Preview mode to visually see the HDRI lights on the product that’s being rendered?
Re: HDRI within Render Preview
This is actually an available feature through RDK. We’ll be adding more extensive RDK support with the next full version, so this is something that you should be a part of it.
