Crash when I try to use cesium-unreal #772

Closed StarsTesla closed 2 years ago

StarsTesla commented 2 years ago

Hi there! Almost two weeks ago when I use the cesium-unreal to display my photogrammetry scene, but today, when I try to start a new ue4 project for my new scene, I found that no matter what I have done, the display is always nothing by using censium-unreal and ion, so I tried to change a project, use the old project, down the version to 1.11, change to the old 3dtiles and even with the ue5. I have done with reinstalling whole UE or the plugin，nothing changed. I also tried to use other scene like CityPark in the marketplace, it shows fine. Is there a solution？

Here are the screen shots： all white after I add cesium sky（all black without sky but with the terrain） a1 - 虚幻编辑器 2022_3_3 0_23_15

Here is the whole crash log： And I found that I even don't need to add a local address，just double click could crash the ue4，the key problem also could be why the ion assets did'n display，the output log didnt give any error or warning when I add the terrain or sky to the world.

I'm not sure what's going on with the access violation, but the all white screen when you add CesiumSunSky is easy to fix. You need to enable "Extend default luminance range in Auto Exposure settings" in the Project Settings, as explained in the Getting Started guide: https://cesium.com/learn/unreal/unreal-quickstart/#step-5-add-lighting-with-cesiumsunsky.

Actually I enabled, so that's the most confused thing.

I found that only I click run then I can see the sky and terrain, preview cannot show me the stuff, but what' wrong with the local tileset, click it will totally crash.

Are you on a remote desktop connection? You could be running into https://github.com/CesiumGS/cesium-unreal/issues/660

As for the crash... I'm not sure. Perhaps there's something wrong with the tileset prevening it from loading, and the plugin isn't handling the focus correctly for a broken tileset. I'd suggest keeping the Output Log open and see if anything helpful is printed there just before it crashes.

Finally，I am sure that the problem is the remote realtime rendering，shit bro thanks~
