Hi @marcomanni,

Can you share more details about your situation so we can better help you? For example,

- Can you reproduce this problem in the Cesium for Unreal Samples?

Sorry janine for the poor detail. I remove the sequence actor and work fine. I dont know why but if i remove it or i remove cesium3dtileset google maps it work. Obviously i remove the sequence and remake it. Now all works very well.
