I'm having some trouble with a scene. I have a character on a bike moving across a plane and a volumetric fog as a sky. The camera is linked to the bike and follows the same path. I have done some renders before which were absolutely fine but in my last render the fog has started shaking and has horizontal tears across it.
I've tried using a new camera, unlinking it to anything and only having the fog visible to the camera but it's still happening, does anyone have any idea what this may be?
