Black cross on Render.

I’ve enclosed a pic of a render showing a black cross in the centre of the sphere. I have a spotlight situated here, pointing straight at the camera to create the volumetric rays emanating from the sphere. If I move my light, the cross moves accordingly. Any ideas on why the cross in my render?


Texture on light? Its best to see the file if you can post it… Unless someone has already run into the same thing…
