fooliage looks bad/pixelated with temporal AA
so i have this problem where grass looks VERY BAD with temporal AA some parts of grassblades are with holes/missing (look picture)
anyone knows how to fix this problem?
-all setting set to epic
-grass is from kite demo (ive changed no setings)
-tried 4.10 /4.9 /4.8
-tried diferent graphic card
-tried diferent OS
here are pictures with AA and without it
This is expected behavior due to the dithering calculations that Temporal AA uses.
So, what happens is the AA method you choose takes a sample from the current scene. Then that sample is calculated and redrawn on the screen a frame behind real time. With dynamic objects this creates a ghosting effect.
TemporalAA requires accurate per-pixel motion vectors. Because you are using WorldPositionOffset (or displacement) to animate, the motion vectors will not be accurate.
What you see is a limitation with AA and such will not be " fixed. " However, the development team is currently looking into options that will reduce how noticeable this effect will be. Thank you for reporting this issue to us. At this time I do not have an ETA for when these improvements will be made.
