使用客户提供3dtiles瓦片,海拔高度2000左右,无论是否使用heightOffset降低高度,都会出现屏幕下半部分不展示瓦片的问题。浏览器警告:mesh with id(3dtiles:id码)was already created.

Research direction

No repository file or test is named. Start by reproducing the issue with the customer-provided 3dTiles data at about elevation 2000, comparing behavior with and without heightOffset while watching for the duplicate-mesh warning. Done means the lower portion of the screen displays the tiles correctly without the warning.
