Hi, I have a curve flow particle system, and i need it to be made up of long particles with a trail like effect.
Can i use motion blur for this? and would i do that in the render settings? or is there a special particle motion blur setting?
Also are curve flow particles affected the same way as normal particles by fields? I need it to spin like a vortex, yet the vortex field does not seem to be working for me...
many many thanks.... i am tearing out my hair trying to get it right...
Motion blur on particles depends on a couple of things. 1.) what type of particle (hardware/software) and 2.) are they cached?
you will have to cached the particles to get motion blur, epsecialy on network renders.
Hardware particles will only render in the hardware rendering engines, and the software particles will only render using maya software/mental ray. I think in version 7, the software particles should motion blur.

Have you tried using Streak or Tube particle types? These particles are by default streaked (or blurred) along the direction of their motion; no need to change any motion blur settings.
As for the effect of the field, curve flow particles are indeed affected by fields, but they are also effected by goals, and (I believe) by default the goals are so strong they override the fields. You will have to lower the goal value of the particles so that the fields can have a visible effect.
