I have a scene of a tank firing confetti and the preview render looks normal.

enter image description here

However, when I render the animation, the entire confetti part stays at something that looks like this.

enter image description here

This is a motion track and the blurry streaks are still moving properly according to the camera movement. Is there any reason why this is happening? Thanks in advance.


It appears that you have Motion Blur enabled in the Render Settings. Motion blur is not currently supported in viewport renders, hence the confetti looking different in the final F12 render.

To disable, simply un-check the box in the Render Settings tab:

Motion Blur

  • $\begingroup$ I had suspected motion blur for a little, but the streaks just stay there, they do not move at all. Is this because I didn't bake the particle system? $\endgroup$ – caleb lee Apr 20 '19 at 21:32
