Why does the actor position change when move camera view

Cesium for Unreal
1

this my code:

// Called every frame
void AAgent::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
	GEngine->AddOnScreenDebugMessage(-1, 2, FColor::Red, FString::Printf(TEXT("%s"), *GetActorLocation().ToString()));
	UE_LOG(LogTemp, Warning, TEXT("%s"), *FString::Printf(TEXT("%s"), *GetActorLocation().ToString()));
}

//
void AMyPawn::MouseXMove(float Val)
{
	if (Val == 0.f)
		return;
AddControllerYawInput(Val * RotationRate);
}

Hi @PeteChan,

Most likely this is caused by World Origin Rebasing:

Hi @Kevin_Ring
I deselected the “keep world origin near camera” attribute on cesium geography but still didn’t solve the problem

Ok, in that case, I don’t know. I’m not aware of anything in Cesium for Unreal that would cause that. Is there perhaps something else in your level causing your Actor to move?

I have the same problem when I try to use new actors
