Multiple Simultaneous Camera Rendering

Hi @harrison, welcome to the community!

Cesium for Unreal discovers the cameras for tile selection with this code:

CesiumGS/cesium-unreal/blob/v2.12.0/Source/CesiumRuntime/Private/Cesium3DTileset.cpp#L1482


      
            case ETilesetSource::FromCesiumIon:
              UE_LOG(
                  LogCesium,
                  Verbose,
                  TEXT("Destroying tileset for asset ID %d done"),
                  this->IonAssetID);
              break;
            }
          }
          
          std::vector<FCesiumCamera> ACesium3DTileset::GetCameras() const {
            TRACE_CPUPROFILER_EVENT_SCOPE(Cesium::CollectCameras)
            std::vector<FCesiumCamera> cameras = this->GetPlayerCameras();
          
            std::vector<FCesiumCamera> sceneCaptures = this->GetSceneCaptures();
            cameras.insert(
                cameras.end(),
                std::make_move_iterator(sceneCaptures.begin()),
                std::make_move_iterator(sceneCaptures.end()));
          
          #if WITH_EDITOR

So, by default, it will use the cameras attached to player controllers and ASceneCapture actors. If you need additional cameras, you can use the Blueprint or C++ API provided by the CesiumCameraManager Actor to do so.
