Unwanted automatic tessellation on terrain

Hello everyone,

So here is my problem, when i create a custom material for my landscape in order to have slopes etc there is a sort of tessellation apearing automatically. It doesn’t happen when I use a very simple material (like in the starter content). In my custom landscape I haven’t enabled the tessellation so I really have no idea why it does that. I set up custom LOD on my landscape too

Here are the screens of my problem and my material.

That is landscape LOD system, and it is working as expected with your LOD settings.

But why is it so dense ? I want the second one not the first. I don’t need tessellation so I don’t need so much détails. What I can’t understand is why the tessellation activates itself with just a simple material.

Check if tessellation is disabled in material settings.

That was it ! I don’t know why it activated itself. Thank you very much :smiley:
