Cesium viewer has a close relationship between the Mesh Level-Of-Detail and the zoom level. In SURE there are two options of exporting the Cesium Mesh that will offer two different possibilities of visualizing the mesh in Cesium Viewer relative to the zoom level.
If the option is deactivated, the Cesium Mesh will no longer be displayed in the viewer, if the camera distance/zoom level to the Mesh exceeds the corresponding minimum Mesh LOD (minimum resolution). This is beneficial for large datasets, due to the fact that less data it's streamed from the server and the rendering process speeds up.
When the option is activated, the Cesium Mesh will always be displayed in the viewer - no matter how far the user zooms out. If the camera is far enough, the minimum LOD will be rendered.
Default value: disabled
-cesium_always_show_max_lod - The mesh will be always displayed in a Cesium viewer while the user zooms out.
