Hi ,
I’m facing this bug with boundless water and this is very visible with underwater objects; 
here is an image that speaks by itself: 
https://ibb.co/bmKSHQW
 
looks like the ripple effect disappears or become low detailed, transition is very rude.
I have tested 10 different plugins versions, same result , this image was captured using trueSKYUE4Plugin_4.26_4.3.7998d1180_x64 version
what setting/truesky command  can correct this bad behaviour ?
 
even with “cinematic” scalability and 4096 profile buffer resolution in water object, this problem occurs 
in truesky actor all water settings at max or min does not change something.
 
Thanks for your support.
