The rendered output doesn't match the real-time viewport preview, and I've tried multiple troubleshooting methods with no luck. why??

What is the shortcut key for re-rendering? And how can I set this shortcut key in Cinema 4D? I have a large number of pictures to create and need the shortcut key to improve efficiency.
