You could use UMeshComponent from which both UStaticMeshComponent and USkeletalMeshComponent derive.

```auto
TSet<UMeshComponent*> MeshComponents;

if (StaticMeshComponents.Num())
{
    for (UStaticMeshComponent* sm : StaticMeshComponents)
    {
        MeshComponents.Add(sm);
    }
}
else
{
    for (USkeletalMeshComponent* sm : SkeletalMeshComponents)
    {
        MeshComponents.Add(sm);
    }
}

for (UMeshComponent* mc : MeshComponents)
{
	if (UMaterialInterface* DefaultMaterial = mc->GetMaterial(IndexOfMaterialToMakeDynamic))
	{
		DynamicMaterialInstance = UMaterialInstanceDynamic::Create(DefaultMaterial, this);
		mc->SetMaterial(IMaterialDynamic, DynamicMaterialInstance);
	}
}

```
