Once again I thought I would give vector blur a try, I generally deem it too low quality to use for any final work. And once again it is producing render anomalies.
Consider this image. It seems that vector blur just gives up processing if it encounters an alpha space?
In this image, there is a white floor plane and the sky is white. When the arrow in motion crosses the horizon threshold, vector blur gives up an produces an unusable frame.
Is there anyway to make vector blur just be on all the time? Why would it quit processing its blur just because the ground plane runs out?
