I have no complains on how vray handles Tyflow MB.
(with exception that I like to see Tymesher have a proper MB)
Anyway, depends on particle setup, and what you want but one of the workaround (if the particles are small (like sparks)), is that you can spawn few particles, after each particle, and make a sort of small trail.
That way, if particles have swirling curvature motion, you could see a nice trails, additionally blurred with MB.
hi, i am using vray, with instanced low res spheres as the geometry. i have 4 sub-steps, and 10's of millions of particles. project is spray coming off spinning tyres in the rain. even with 4, or 8 geometry samples in the motion blur settings, i get only perfectly straight motion blur trails from the droplets. given that their trajectory curves significantly over the course of a frame, this makes things look a bit rubbish.
if i am missing a setting somewhere and curved moblur is poissible id love to know what im doing wrong!
its a nice idea to spawn a trail behind each particle, but im already at 5-6 hrs sim time, and 12 hrs to render a still, with 70 gb ram use. adding a trail to each of the particles would kill my machine i expect! -i might be able to use this method on the flow for the larger drips closer to the tyre, of which there are many less.
