Update instances PFlow Motionblur

[jp3d81]

Hi,

i always asked me if i am doing something wrong, when i render particlesystems in vray.
In my case i have a cached particle-system, which i want to render. Everything ok until i use motion blur.
If i use it, vray starts to update the instances before rendering and it takes more than the final rendering.


Is it normal, or am i doing something wrong? Is there a trick to make it faster?

I'm not entirely sure what happens here. A scene would be helpful.

Best regards,
Vlado

Ok, i found my mistake. I did a fullframe cache. So vray started the calculation for the missing integration step on rendertime.
With the motionblur settings i did. The cache has to be at "integration step" 1/2 Frame.
I am not a particle pro, maybe a notification could be really helpful.
