Hi everyone!
I was having the same problem but I think I found a solution. I have been exporting some test and there is not more flickering and glitchy stuff. And also the point looks more consistent, their density and the size. Everything looks like what I was seeing on the original scene inside of UE
In the movie render queue I am adding these things on the exports settings:
In the export settings first selected console variables and add these settings.
r.ScreenPercentage 200
r.LidarBaseLODImportance 0.1
r.LidarPointBudget 1500000
r.LidarTargetFPS 59
r.LidarIncrementalBudget
r.LidarScreenCenterImportance 0
I got that information from here:
And I am also adding an Anti-aliasing:
Simple sample count 1
Temporal Sample Count 64
And check the Overide Antialiasing option
And the result, I just created my account so I cant upload more images of videos, sorry
