recently i implement a temporal aa, everything is ok, but the stair is flickering when camera is static.
i don't find any material about anti-flickering solution, except the ue4 taa paper <<High Quality Temporal Supersampling>>.
but it don't contain the detail implemention.
i find in ue4 shader code, i found it pass a low-pass filtered color to the neighbor aabb clip function.
and it seems in default ue4 don't do the low-pass filter, the low-pass filtered color just = current color.
anybody have some solution to solve the noisy flickering?
thanks.
