+## Low-level UObject creation api
+
+Til now you have seen how to create new UObject's in a very pythonic way:
+
+```python
+from unreal_engine.classes import BlueprintFactory, Material, MaterialFactoryNew
+
+bp_factory = BlueprintFactory()
+material = Material()
+# the first argument here (None) is the outer UObject
+material_with_a_name = Material(None, 'FooBar001')
+mat_factory = MaterialFactoryNew()
+```
+
+While the automagic python UObject creation api is really handy, sometime you want lower-level access to the ```NewObject<T>``` C++ api:
+  
+```python
+import unreal_engine as ue
+from unreal_engine.classes import Material
+
+material = ue.new_object(Material, None, 'DumbMaterial001', ue.RF_PUBLIC|ue.RF_STANDALONE)
+``
+
+or for more dynamic class specification:
+
+```python
+import unreal_engine as ue
+
+# you can reference to Unreal classes with a string
+material = ue.new_object(ue.find_class('Material'), None, 'DumbMaterial001', ue.RF_PUBLIC|ue.RF_STANDALONE)
