Cesium crash , but why ?!!

Hi there !

I’m preparing a short movie , and I’ve just discovered the amazing Cesium plugin to get 3D google map inside the Unreal engine.

But When I’m processing a video , the engine crashes.

I’m wondering if someone could help me understanding the error message :

I’ve dicresed the zone with a polygon , of course , to make the calcul smoother , but nothing changed…

Yet my area is not that big…

Thanx for all your answers !

Same issue, with almost same error, but on line 2049 Cesium3DTileset.cpp.

Hey dude , sorry for answearing so late !!!

I’ve solutionned my problem with decreasing the LOD of 3D cesium map. And it worked :slight_smile:

Sure , you’ll have to adapt the LOD with the kind of project you do. Here , to obtain a skyline , my LOD is at 16 , but the first plan is , of course , at higher level . You don’t need to have a high level of detail for skylines. Only in close camera plans.

Hope it helps.
