I can get motion blur to work in perspective with particles to create a waterfall. When I switch to any Vray Physical camera I can’t get any motion blur. Doesn’t matter whether I have motion blur turned on or off in general camera settings or motion blur ticked on in the camera itself. Am I missing something?
It’s probably working but your shutter speed is too fast to show it. Change it from 200 to something lower and it should show up.
In any case if you want you can change the moblur duration on a per object basis (vray object properties)
