If a SceneCapture2D actor is in use on the map then the temporal AA has shimmering artifacts on moving objects:

Hi ZoltanE,

Thank you for the feedback. I was easily able to reproduce this in 4.4 and in our current internal build. I have entered it as TTP# 344125 into our tracking software and our developers will be looking into the issue.

Thanks, TJ

To make sure we see the same artifacts - is your mesh translucent? Have you disabled TemporalAA to verify that is the issue (in game console: “show TemporalAA”) ? You also can try to disable MotionBlur (“show MotionBlur”).

The mesh uses a very basic material: Surface - Opaque - Default lit - No Tesselation.
Yes, the shimmering only happens with TemporalAA turned on AND having a SceneCapture2D running.
MotionBlur doesn’t really change the AA artifacts which are still visible unless the pawn is blurred into a smudge.

Bump!

Hi hurricane86,

Please bear with us, this is still being looked into by our dev team and has steadily moved up in priority.

Thanks,
TJ

Hi, just another bump FYI :wink:

FXAA give results not comparable with TemporalAA - especially when used with SpeedTree.
