Mesh have no physics

After creating one of the resource node meshes and setting the parameters so that it could fall according to physics, it doesn't work, the model just flies in the air and don't want to fall.

AActor* NewActor = World->SpawnActor<AActor>(AActor::StaticClass(), FTransform(Location + FVector(0.0f, 0.0f, 1000.0f)));
if (!NewActor) return false;

UStaticMeshComponent* MeshComponent = NewObject<UStaticMeshComponent>(NewActor);
if (!MeshComponent) return false;

//

MeshComponent->SetStaticMesh(ResourceNodeInfo.Mesh);
MeshComponent->SetMaterial(0, ResourceNodeInfo.Material);
MeshComponent->SetMobility(EComponentMobility::Movable);
MeshComponent->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
MeshComponent->SetCollisionResponseToAllChannels(ECR_Block); // ?
MeshComponent->SetMassOverrideInKg(NAME_None, 100.0f); // ?
MeshComponent->SetEnableGravity(true);

MeshComponent->RegisterComponent();
NewActor->AddInstanceComponent(MeshComponent);
NewActor->SetRootComponent(MeshComponent);

MeshComponent->SetWorldLocation(Location);

MeshComponent->SetSimulatePhysics(true);
MeshComponent->AddImpulse(FVector(0.0f, 0.0f, -100.0f)); // ?

AActor* NewActor = World->SpawnActor<AActor>(AActor::StaticClass(), FTransform(Location + FVector(0.0f, 0.0f, 1000.0f)));
if (!NewActor) return false;

UStaticMeshComponent* MeshComponent = NewObject<UStaticMeshComponent>(NewActor);
if (!MeshComponent) return false;

//

MeshComponent->SetStaticMesh(ResourceNodeInfo.Mesh);
MeshComponent->SetMaterial(0, ResourceNodeInfo.Material);
MeshComponent->SetMobility(EComponentMobility::Movable);
MeshComponent->SetCollisionEnabled(ECollisionEnabled::QueryAndPhysics);
MeshComponent->SetCollisionResponseToAllChannels(ECR_Block); // ?
MeshComponent->SetMassOverrideInKg(NAME_None, 100.0f); // ?
MeshComponent->SetEnableGravity(true);

MeshComponent->RegisterComponent();
NewActor->AddInstanceComponent(MeshComponent);
NewActor->SetRootComponent(MeshComponent);

MeshComponent->SetWorldLocation(Location);

MeshComponent->SetSimulatePhysics(true);
MeshComponent->AddImpulse(FVector(0.0f, 0.0f, -100.0f)); // ?

Solution:

Yeah, but it's still levitating. I think my problem is gone, I just create BoxComponent, attach mesh to it and it works fine

nothing looks out of place in the snippet you sent, but I have never tried this before

That should be enough to make a mesh fall
