Arnold HTOA: I’m putting my note here to create a motion blur AOV for packed instances. I do everything inside Houdini for lighting and rendering.
I will describe my understanding of packed geo and packed fragments as well.

The Arnold version I used for this note has been updated to pick up any native or packed geo/fragment and generate motion blur for it, with no extra steps required for the procedural workflow using the Procedural Object Node, as in the previous version.
HTOA 6.2.5.1
Arnold 7.2.5.1
