Like this BorisFX tut, How to replace objects with heavy motionblur?
Is there any detailed explanation about this topic?
If you Render using the Insert Module, there is a tick to enable motion blur. Find this under Insert Modual>Comp>Render Motion Blur. If you have the Mocha Pro plug-in, then you can render out as an Insert Cutout to comp back in your host.
Note there is not much manual control over motion blur render in Mocha, so some users might use other techniques (depending on the host) to regenerate motion blur.
