Waterbodies are not transitioning correctly. I’ve seen others creators run into this with their Islands as well. This appears to be an asset material issue.
FYI - I changed the water transition materials to the ones from the ocean. Even with these you will still notice a hard edge between the waterbodies in some areas.
Have the same issue and it looks terrible. See below how there is lines and a gap between when the river meets the lake. When can this issue be fixed? Or what is a work around?
