Upgraded from 4.26 to 5, my plants and Niagara FX now have this odd motion blur

I tried deleting my post-process volume, no change. Anyone know the cause?

I would try setting motion blur amount and max to “0” in the details panel of the post process volume.

Hi, thanks for the tip.

I set both settings to zero and the blur effect persists, so I wonder if it’s coming from another source. It doesn’t look like the normal post-process motion blur. Again, this effect wasn’t visible in 4.26, so I’m assuming it has something to do with a change in 5.0.

Looks like the same issue as this post:

Looks a lot like pixel dithering or anti-aliasing ghosting.
