Hello everyone, I don’t know English well, I use a translator. I am creating videos on an unreal engine, I recently upgraded from 26 to 27. on a new version of the motion blur problem. Help fix this

if you’re using MRQ, you should increase the temporal samples, and try changing the camera shutter speed (motion blur) from 0.5 to 1
does not work((
at these settings double frame is corrected, but the quality of motion blur is terrible
if you set the value of temporal sample count to more than 1, then the frame is doubled
try 4 spatial, 4 temporal
higher quality render takes more time
if you want to save time, you try turning on anti-alias to TAA as well
is it possible to get an answer from the unreal engine developer?
I have the exact same problem i turned off the motion blur but my render looks like this
I don’t know what to do
I didn’t find a solution to the problem, returned to 26
Same problem and no solution. Tried everything but nothing helps. Seems like a bug that needs fixing.
I also think so, we need to wait for the next version of the engine, sadly version 27 is very cool, the same RTXGI plugin that improved the picture without losing FPS

Just accidentally noticed what is the problem. I turned on frame blending in AE and noticed the same effect like the issue with motion blur.
Essentially, I think Unreal just overlaps 3 frames instead of applying subframes when calculating the effect. Definitely a bug. Shutter speed, cvars, tweaking different parameters… nothing helps
+1, experienced the same artifact.
