Weird Motion Blu (?) Artiface

Development Rendering

UE 5.3.2. I’m having weird flowy/flickering/shimmering artifacts. I dunno if they are because of motion blur, but I managed to rule out all usual suspects (SkyLight, Lumen).

They happen when I simulate a Chaos fracture and then pause. Also, they are only apparent in objects that were moving before the pause. Once the rocks become stationary, they disappear.

I practically scoured the forms/subreddit and found nothing. Any help would be much appreciated :slight_smile:

interesting look. that are frozen motion vectors. the parts, even while frozen, have velocity that is used to compute motion blur and parts of the taa/tsr histogram. you can view that in the velocity buffer visualization.
