Weird Motion Blur trails Tweet

[Mentaldevil]

Hello,

I wanted to render a simple particle explosion shockwave with a low amount of particles but lots of motion blur (around 400k particles, Shutterspeed 5 seconds). Additionally, the particles are moving very slow. This seems to result in some weird motion blur behavior (trails shooting in the wrong direction). Let me know if this is fixable and if you need the scene files for more info. Thanks!
