rawLight elements are different by Progressive and Adaptive Sampler

[flat]

The rawLight elements with motion blur are different by Progressive and an adaptive sampler.

What is a cause?

Tested environment:
Maya 2016 + VRay 3.40.06 + Windows
Maya 2017 + VRay 3.52.01 + Windows

I generally don't recommend using the raw elements directly out of V-Ray - it's better to reconstruct them in post by dividing the lighting element by the diffuse element. When you use the adaptive sampler, V-Ray attempts to do this automatically for you whenever all three elements are present in the scene. However there is no easy way to do this for the progressive sampler.

Best regards,

Thank you for advice.
I forgot to be able to create RawLight from Lighting element.
