Screen Space Reflections do not update on scene capture 2d
Hello. I'm not entirely sure this is a bug or if it was meant to happen but using a scene capture 2d when it does not update every frame causes the reflection environment to not show up. Every other option works and toggles just as it should, just not the reflection environment. I have one setup that teleports to different socket locations and captures a different scene. I also have the tick set for every .0416 seconds and I update the scene capture content on that to control the FPS of the scene capture. Really helps out, I have two 780Ti's and one scene capture at roughly 1366*768 takes from a consistent 120 to about 96 fps, with one 780Ti pumping I go from about 120 to about 60 or so. Limiting it to roughly 24 fps with the tick and updating the content maintains a consistent 120 FPS but the reflection environment does not show up. So I just toggle whether or not the render itself is active but that causes pretty radical fluctuations between 95 and 60 FPS but that keeps the reflection environment visible, which in what I'm making is a fair amount of important in making the environment believable. I'm not sure why not updating the capture every frame doesn't capture the reflection environment. I get why activating and deactivating it does, it just does not save enough frames. having some sort of FPS limiter on scene capture 2d's without diving into too much source would be fantastic if they become important enough.
Hi MrAdAbsurdum -
Thank you for your patience. I was able to replicate this issue internally and have placed a bug report in to investigate a solution to it, for reference UE-22321.
As we investigate and get new information I will keep you informed here.
Thank you again for your help in tracking down this issue.

I now got what I think is a similar issue. I have a reflective plane, and several SceneCapture2Ds. When I do the capture, they all have the screen space reflections of the pawn. which are very different, because the SceneCaptures 2D are in different areas.
I have tried the "capture every frame" trick and also set some priorities but nothing helps. Even disabling the "Screen space Reflections" in lighting features show flags" in the advanced parameters of the screen capture doesn't seem to have any effect.
