Strong temporal AA ghosting

Hello.

I’ve just downloaded 4.15 version and discovered that ghosting effect is much stronger than before, it’s visible even in Example maps.

Repro steps:

  1. Create a Third-person template project and open it
  2. Press Play
  3. Stand against shadowed wall
  4. Rotate camera

Thanks,
Dmitry.

Easy fix is to just turn off motion blur.

But there are some settings you can tweak to mitigate this. Sharp Temporal AA - Rendering - Unreal Engine Forums
