I can't display local terrain without an internet connection

Cesium for Unreal
1

Hi,

i try to display terrain and building from my local machine.

If my PC is connected to Internet, it works with:
file:///C:/Temp/MyTerrain/terrain/tileset.json
and using a server:
http://127.0.0.1:8080/MyTerrain/terrain/tileset.json

But when i do the same thing without any Internet connection, my terrain is not loaded (i just have a gray area near the camera).
My terrain is local, why do i need Internet ?
How can i solve the problem ?

Hi @Greg2021,

That’s odd - I haven’t heard of this issue before. You shouldn’t need internet to load from your local disk or a local server.

Can you try testing from a local server in CesiumJS? You can use this sandcastle to get started. Please let me know if you’re able to get it working with CesiumJS.

Also, can you let me know if you’re getting any errors in the Output Log when you try loading without an internet connection?

Hi,

i have found the source of the problem.
I have modified a Cesium3DTiles which was using CesiumIon to use my local 3DTiles, but i have not deleted the Cesium Raster Overlay from Bing.

Sorry.
Thanks.
