Description

From AnswerHub:
Second one is that Motion Vectors are bugged for some objects. This causes lot's of temporal artifacts. Third picture lamp is good example of bug. Lamp is static. Camera is not moving.

Steps to Reproduce

Fastest way to replicate Motion vector bug seems to use ShooterGame and Open project settings -> Rendering -> toggle Accurate Velocities from Vertex Deformation and Selectively output to the GBuffer rendertargets ON.
We also tested with another Mac and bug was reproducable. There is screenshot from bug with First person project when changing only those two settings.
