I'm using Zylann's terrain add-on to generate terrains in-game based on real world regions. The generation is for now going pretty well, but I have met a big issue with the plane I wanted to use as an "ocean" mesh : it just glitches as hell when I zoom out or zoom in from the map, in the editor.
Indeed the issue apparently disappears when I launch the game ; but I'd like if possible to be able to play with the scene without having my eyes melting because of this glitch.
The mesh material not related since the issue is still here.
Here's a video on the thing: https://streamable.com/z2259k
Thanks in advance.
