I'm doing a motion blur test in maya and trying to use the motion vector pass
So far I have no problem in rendering the mv pass in maya
the mv pass and the original layer are perfectly match and without any offset
As you can see my attached image, however, there are some undesired sharp edges appear between the ground and the moving object, seems the RSMB vector fails to calculate overlapped objects with different moving direction/speed.
SO my question is: is it normal? or I missed any steps? How can I fix it without exculding the ground from the vector pass?
