Like mantra, deformation/transformation blur as well as velocity
blur are offered. Similar set up - on mantra velocity blur on the
object is set, and on the mantra node you check on motion blur. In
redshift it is similar. You must select Mesh Deformation Blur
from velocity attribute as seen in the figure below
Velocity Blur
In Redshift, if your geometry has velocity (or you can add a trail sop to compute velocity) you can use this for motion blur.
Change your object settings to include Velocity Blur as well as your Redshift ROP as follows:
motionBlurRedshift.hiplc example file
Additionally you can post manipulate motion blur to control the effect
You can also use motion blur without a velocity vector, just deformation (using $FF). That would not require you to check the object container v option, but you also do not get the advantages of control (as well as most fx systems will have a v vector, such as particles).
