How to capture FSR2.2 effect by scene capture 2D in UE4.26

[ccysway]

Hi,
I'm using scene capture 2D to capture scene to a render target 2D texture.The FSR is effective in viewport,but I can't get the fsr effect in render target by scene capture 2D.I found scene capture 2D actor just have TAA or FXAA. Is there any way to capture FSR effect by scene capture 2D? Thanks in advance!
