Motion Blur not working on SceneCapture2D

Dear Gaming Heads!

I know it is difficult to create something that works properly if your only customers are kids and gamers, but motion blur does not work in SceneCaptures2D. I write a render target to disk in blueprint, the render target in linked to SceneCapture2D/FinalColor and all motion blur flags are on, still nothing on the written frame. I can even visualize the velocity map and it is there while the frame is written, but nothing.
So I am not sure. If you are done creating ultra violent games and suing kids because they cheating in your strange monster games, maybe enter adult world for a moment and fix this? I believe in you! You can survive the adult world, do no be afraid!

Yours sincerely!
