Open level too slowly


I created two levels in ue4, one of the levels(A) loaded multiple 3dtiles, and another(B) loaded a few buildings. Now I want to open level B from A but switch too slowly because level A has too many pending requests that are blocking the main thread. How to cancel all pending requests before opening Level B?


Make sure you’re using a recent version of Cesium for Unreal, after v1.19.0, because the situation was improved in that release. But if you already are, there’s probably not too much that can be done about this right now, as there’s no way to cancel requests. You can try reducing “Maximum Simultaneous Tile Loads”. Or if the network response time is the issue, finding ways to reduce your server’s latency will make a big difference.
