Hi everyone, in this tutorial i will show you how to use the subclassing and Slate APIs in the python plugin to develop a new UFactory for importing collada files as StaticMeshes
# Writing a Collada StaticMesh importer/factory with Python
In this tutorial we will see how to use the advanced subclassing api available in the Unreal Engine 4 Python plugin, as well as how to build Slate GUIs
This tutorial has been tested with Unreal Engine 4.16 and Python 3.6 and assumes you are already familiar with installing the plugin into the engine and editing Python scripts.
If this is your first experience with the Unreal Engine Python plugin, this link is a good place to start: https://github.com/20tab/UnrealEnginePython/blob/master/tutorials/PlottingGraphsWithMatplotlibAndUnrealEnginePython.md#installing-the-python-plugin
The objective is to instruct the editor to import .dae (collada) files as static meshes, by building a new Factory.
A Factory is a special class in Unreal Engine 4 allowing to create and import assets. There are factories for fbx's, wav's, images and all of the media files supported by UE4.
You generally create new factories by subclassing the UFactory class in C++, but in this tutorial we will see how to subclass UE4 C++ classes in pure python.
## Subclassing UFactory: PyFactory
The subclassing api allows the developer to subclass any UClass (classes exposed to the UE4 reflection system). Unfortunately the UFactory class does not expose
its methods to the reflection system, so an handy class named 'UPyFactory' (it is a simple subclass of UFactory) is exposed by the python plugin:

I saw this a few months back I think, just didn’t realize quite how insane it was. The level of integration looks amazing.
I made it crash, though to be fair my first experiment involved trying to create a python class derived from a blueprint derived from a python class derived from a C++ class, which probably wasn’t very kind.
Incredible work, definitely going to dig into this when I have some more time.

LOL, well i will try to support this kind of inception too
Sooo… .dae importer is real?
