[![]( " - YouTube") ](https://www.youtube.com/watch?v=L6TFpfhZVYQ) 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. ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/6/9/76905aeac2f789b2fbabdd5be3aad7b5bdb0754c.png) ---

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: > [@WPO issue in UE 5.0 on all materials, severe smear/dither](https://forums.unrealengine.com/t/wpo-issue-in-ue-5-0-on-all-materials-severe-smear-dither/515780): > > All materials that use WPO for animation have this issue. For example, this is the [Megascans trees](https://www.unrealengine.com/marketplace/en-US/product/megascans-trees-european-black-alder-early-access), the ‘BlackAlder\_Asset\_Zoo’ map: (It might not be fully visible on the compressed video, if so, please try downloading the mp4 file) Is it a known issue? It’s quite hard to miss. Update: Some materials seem to be ok, for example, my grass material in Dynamic Grass System.

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