I'm new to Blender and I've been practicing by creating a model of a monitor with a screen that shows a image of a piece of software.
When I preview or render the animation there is an odd black shape that is cutting through the ground object and backdrop cylinder object (see left of attached image) but not in my stage (right side of image). It changes shape as the camera moves around so I thought it could be a random shadow being created but cannot work it out.
Thanks in advance. James
