To remove material ID (Index Zero)

void FMaterials::Apply(UDynamicMesh* &TargetMesh, const TObjectPtr<UDynamicMeshComponent> &DynamicMeshComponent) 
{
	if (!IsValid(DynamicMeshComponent))
	{
		Message::Error("FMaterials::Apply -> DynamicMeshComponent is NULL");
		return;
	}

	TArray<UMaterialInterface*> CompactedMaterialList;
	if (MaterialsList.Num()>0)
	{
		CompactedMaterialList = MaterialsList;
		CompactedMaterialList.RemoveAt(0);

		UGeometryScriptDebug* Debug = nullptr;
		int MissingMaterialID = -1;
		TargetMesh = UGeometryScriptLibrary_MeshMaterialFunctions::RemapToNewMaterialIDsByMaterial
		(
			TargetMesh, 
			MaterialsList, 
			CompactedMaterialList, 
			MissingMaterialID, 
			Debug
		);	
	}
	
	DynamicMeshComponent->ConfigureMaterialSet(CompactedMaterialList,true);
}
