why i have to set modelOptions for Cesium3DTileset

for me the loading of the tiles only works if i set this parameter for Cesium3DTileset
tileset.modelOptions = {}

Does anyone knows why?

Are you able to post your tileset or sample code? I can’t see why setting tileset.modelOptions = {} would make any difference.

Never mind I see your other question, I’m looking into it now.

Yes, look here
