Unable to display some default 3D tiles on map

Hi there,

I am new to cesium. i am using openlayers with ol-cesium to display cesium ion data.

For now i started with default assets from assets depot.

i tried “Aerometrex Denver Photogrammetry” and i can see it on the map.

but when i tried “New York City 3D Buildings” i cant see it on map.

both are of the same type 3Dtiles. can anyone tell me the difference between both.

Thank you

Are there any errors you are seeing in the browser console?
