Do you have motion blur on?
Thanks for your reply.
I have now turned motion blur on and indeed I now get a velocity pass but - why would I need to render out a velocity pass if I’ve rendered out motion blur in any case?
I thought the whole point of a velocity pass is to have much quicker renders - since rendering motion blur is normally expensive - and using the velocity pass later in a comp to get ‘cheaper' motion blur?
That’s certainly the case whenever I render out animations in Blender and want to control the amount fo motion blur later in the comp using the velocity pass in Nuke or Fusion.
Or do I misunderstand how RPR renders?
