Description

Also tried using “show VisualizeTemporalUpscaler” and noticed the frames that have missing
motion vector data showed up as pops in the “show VisualizeReprojection” part of the
visualizer.

Steps to Reproduce

1. Open the test project provided by customer
2. Start PIE
3. Press “R” two times to show post process shader displaying velocity
4. Press “Y” to render at 30 FPS
5. Observe correct motion vectors on the torso portion of the character with an without physics simulation (Toggle using “T”)
6. Now cook and launch the project
7. Press “R” two times to show post process shader displaying velocity
8. Press “Y” to render at 30 FPS
9. Observe intermittent frames when motion vectors get missed on the torso portion of the character when physics simulation is enabled (“T”)
10. Observe correct behavior in cooked build by disabling physics asset (“T”)
