So,I’m using TAA and when i walk and rotate the camera around my character,it ghost with the foliage behind(that have WPO),if i disable “Vertex Deformation output velocity” then it doesn’t happen,but then i think motion blur don’t work with it(right?)
Things that i tried:
Disable motion blur
Setting foliage to “Movable”
Setting “BasePassOutput=1”
i tried with ue5.5 and it still happens
So,what do i do?
Normal.
Nothing. Thats’s TAA.
You can makenit a little better by outputting WPO velocities in the base pass and setting up to spend rendering MS on fixing the ghosting a bit, but it’s not a cure all or much better in practice…
People generally disable motion blur if they can. The engine does some pretty bad motion bluring. Doesnt mean you should disable it, just dont rely on it for a clean render…
That’s normal, it’s called disocclusion and it’s likely Lumen doing it. If Lumen has no knowledge of the scene behind the character, then it will take time for it to adjust after disocclusion; since Lumen temporally accumulates over time.
