When I render with “transparent background” checked (in the Render Tab) the background does not render but renders as black. Maybe I’m not remembering correctly but I recalled last wip we could render with transparent background checked and Rhino would still render the background. Then when we saved the image checking alpha (the option under the rendered image when we save it) Rhino saved the image without the background and unchecking save alpha saved the rendering with the background rendered.
Am I remembering correctly? Now I have to render twice once with transparent background checked and then again with it unchecked.
