# Motion blur still showing after particles hit a sticky plane

Here is a simple particle system hitting a plane with the collision on and also with a high stickiness.

The objects marked with red have already landed and still have motion blur. The orange has just landed.

For comparison motion blur vs turned off:

How can I fix this?

Edited:

If this is really a bug, as commented on @Yann Masoch's answer, is there a workaround? probably converting the particles to rigid bodies, a mesh, a compositing trick, etc.

In your case, you will have better results with the following Motion Blur settings:

1. Position: End on Frame
2. Shutter curve: 1st curve or 3rd curve (sharpest image)

Just play with the Position and the Shutter curve to adjust the Motion Blur effect.

• Thank you. I will play with the settings. Oct 15 '18 at 21:34
• It is better but still shows the blur. It feels like a bug on the particle system. I will leave the question unsolved for now to see if there is another walkarround. Oct 15 '18 at 23:23
• I did a lot of tests and the issue is coming from the particles but I have different and non consistent results between Cycle Render and Blender Render. I will investigate that later! Oct 16 '18 at 0:07
• I think I figured out the issue... it took me a while! Every time you change the Motion Blur settings, you have to restart the simulation from the beginning in order to have a correct render. Oct 16 '18 at 2:22
• Good. Keep us posted when you have a solution! Oct 16 '18 at 3:12
