Rifts and undulations in the ground when using multi layers

I used terrain with one image layer and it was perfect but since i am using multi image layers , the terrain has rift and undulations . what is the problem?

Hi @ma_se , You can please explain your issue with more detailed information with the help of a sandcastle example or screenshot? It will be helpful for us to understand the issue.

this is what i see

this is important part of code :

  let terrainProvider = new Cesium.CesiumTerrainProvider({
    url: `${process.env.REACT_APP_TERRAIN_PROVIDER_URL}`,
    requestVertexNormals: true,

I can’t see the attached screenshot. Please re-upload it with detailed information.

I just edited my post

Can you please the URL of Terrain Provider here to test?

No it is custom terrain. Is it the problem with terrain?
