Houdini and Redshift Motion Blur

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:

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).
