Shown here: https://gyazo.com/cc688fe606a1aecb2d237d3f5a3b9e16 is me trying to combine regular bricks with water terrain for a river. This is the edge of the map. Is there a way to get rid of the error without just covering it up?
Edit: Please note I haven’t used terrain much at all since 2012.
Qqtt991 has the right idea. Alternatively you can move the Part back and show more of the water instead.
Also, I’m trying to reproduce this so I could give you a more accurate answer, but I’m unable to. Can you describe how you achieved this? Just in the interest of having a solution for the next dev with a similar problem.
