Not rendering properly

I’ve come across a problem with rendering that I’ve never experienced. I’m wondering if I have hit some button by accident. I’ve rendered it at full scale and at the preview scale with the same results. I don’t have motion blur or OSA selected. Does anybody have any suggestions? I’ve attached an image to show the problem. Thanks so much,


Looks like you have Fields selected in the render settings.

yep, that was the problem. Thank you so much!
