particles velocity

Recommended Posts

hello!

i have some problem. i've created the pop network and the particles move by 'position' node, so V [velocity] is not changing (in detail view). and i think cause of this i can't render motion blur.. can't i somehow calculate the velocity?.. or any other suggestions.. thanks..

drop a trail sop after your particle sop and put the switch to "compute velocity".

should work fine then. maybe you have to put a cache sop in front of the trail.

thank you very much for fast reply, i'll try! \and maybe i solved it by changing 'position' to 'velocity' node with accordingly changing expressions) ( P = V*AGE =)

(but when motion blur is on it renders all black...)

(everything solved - the size was too small and blur was too large))
