Particle flow and vray motion blur.

[^Lele^]

try switching the rendering type for PFlow to mesh per particle.

Will send the file in a bit...also will try your idea LeLe cheers. Had to finish off the scene today, so not much chance to get the file across yet.

I'm having this problem too. I have a pflow event with 2000 particles with tetra shape.
If i turn off MB renders fine, if i turn on i get the unhandled exception error.

I have 3dsmax 2008 and vray 1.5 SP2. I need a solution to this.

Im just running into this pflow vray motin blur issue. I can see how it's a problem, and my errors only happen over backburner with a vague "Unhandled exception error". But it's definitly because of particles and motion blur.

I wish that vray could just ignore motion blur meshes that only have existed for one frame. They're usually offscreen anyway.

Have you tried the camera culling operator from the freebies? it cuts geometry that is off screen with a threshold to thin out memory demands. Not sure if it works with vray but definitely worth a shot!
Also make sure the particles have the same sub frame sampling as the vray mblur (1/4frame and 4 samples in vray e.g.).
