Cesium for Unreal Serves only zero level of local terrain

Hi Everyone

I have a terrain dataset with layer.json.I am serving them using http server.for use dataset I create a blank 3D tileset from unreal and select from url option than I give my url

when I refresh the tileset creates a terrain like that

and webserver just serves the zero layer

my terrain data is here
terrain.zip (142.2 KB)

Thanks Can

While Cesium might only load the first two layers at first, as you move around the globe, it should load in the other layers. It seems like your dataset only covers a small portion of the earth, so you’ll only see additional layers loaded when you’re zooming in to that area. Try changing the editor view into wireframe (top left “Lit” next to perspective, click “Wireframe”) and increasing the camera speed (top right, camera icon, drag the slider up to max and set the multiplier to something like “4.0”) and try flying around - you should see tiles load in.
