how do i render multisegment motion vectors in mentalray and can i export those to AE?

There's a selection for "Motion Steps" in the render settings. That will look at the motion vectors more during the frame and smooth out non-linear motion.

If you need a color vector pass, La Maison has a shader for Reelsmart and the Production Shaders also have a vector shader. Reelsmart does not use the blue channel I believe.

i use lm2dmv.. for motion vector pass... but i still have the problem where the object that overlaps. it gets weird result. Does it only work for one object

Have to keep in mind that post blur just smears pixels basically. So objects behind something that is blurred get covered by the smeared pixels.
