Short description of error
When rendering with eevee, motion blur is only applied to the beauty pass. Other passes such as cryptomatte or normal dont have mblur applied, but you can see the steps of the accumulation blur in some passes. This is a huge problem for compositing, it makes all the passes mostly useless.

Exact steps for others to reproduce the error

  • animate an object
  • turn on passes
  • render with eevee with mblur on
  • check the aovs, there will be no mblur on them

Here is the result of the output aov2 (I must have seen something wrong but I expected only 1 object):

Anyway, the motion blur is not as expected.
