Dear Mcneel Team,
I have a question about the RenderBlowup command. In my case, it doesn’t work on Mac or Windows in Rhino v8.
I’m a lecturer and curator of first-year students at ETH in the architecture department. I’m looking for the most efficient render workflow in Rhino. We’ve been very happy with the results so far, but now that we’ve a workflow to find the best 2-point perspective model alignment, we’d like to crop the render. After researching, I haven’t found any supporting information on the RenderBlowup command.
According to your documentation, the RenderBlowup command renders a selected area of the current viewport in the render window at the resolution specified in the Rendering panel.
In the attached screenshot, you’ll see that my custom resolution is now astronomical, but it still renders in the viewport resolution. Could you please help me determine the correct direction to take?
Thanks a lot,
Best regards,
ivan
