Was just testing the PR motion blur on some geometry and noticed that when multiple scattering is activated PR does not render the shadows on a density volume. Not a real issue as I very rarely use PR but may need looking into for TFD v 2. I realise PR-MB will not work on the TFD but I wanted to see if I could do a TFD pass that takes the motion blur into consideration ( behind a spinning propeller)
Any thoughts Jascha ?
Have you tried setting the illumination to ‘Accurate’?
You can take a decade off while it renders…

Haha! I returned to this after posting another thread about how to get the result I need, and realized that you very subtly revealed it here!
If you turn multiple scattering OFF completely under Physical Render, it works just like with it on under Standard 
I have wasted a day and a half on this - thanks so much! You hardly even had to say another word!
