motion vector 2004-03-16 - By luc froehlicher
Back
this problem is inherent to the 2D motion blur technique.
same problems happens when an object enters frame or transparent stuff...
We are currently integrating depth infos into the process , it solves
parts of the problem (but not all)
you can also render your frames with no mb , then camera project the
frames back on your geometry
through a constant shader and render with 3d mb.this would be an
intermediate solution

ok! it realy works, thanks
but how i can be with crossover objects?
in that case, i can render objects separately, but if i have many
legged character?
i won't render each leg separately ;)
