My laptop battery died while I had a Rhino 7 file open and when I opened my file the lighting was wrong (surfaces not showing layer colour in shaded mode, and contrast too high in rendered mode). I tried copying to a new file to ensure default settings were correct but all my Rhino files are showing the same problem no matter what I do. I have also tried reinstalling. Additionally, when I do ViewCaptureToFile no image appears. Can anyone help with this please?
Did you checked if Rhino is using the Hardware Driver in the Advanced Settings ?
