Hello , thanks for reply , i think there are users already discuss about that.
Like i said previous thread , I tried solution to server 0.terrain only for every xyz terrain requests , it work but keeps flickering.
I have provided video link and also you can see CesiumGeoreference origin is fine as well.
My requirement doesn’t need to 0 elevation, but need to even flat surface. for example if elevation is 60 , i need all elevation 60 , otherwise moving gameobjects are not usable on ground on default terrain.
Please have a look at video link , it is dropbox link
