Visual flaw showing movement trails

I have started development on a new level and when I went in to see what the floor texture looked like in game, the gun and player were displaying residual movement trails.

This is what it looks like.

Can anyone tell me what the cause and fix is?

Edit
I know its not motion blur because its not turned on. I also turned post process to zero so I know its not that.Thank you.

The cause is Temporal AA.

I found the temporal aa setting but it cant be modified, it appears to be locked. Any suggestion how I can address the issue?

Disregard my last post. Silly me I forgot to add a post process volume to the map… Moral of the story… Add post process volume to your map and switch to fxaa from temporal aa. :slight_smile:
