Accessing Editor Source Code for Importing Objects

Hey everyone,

can anyone tell me if there is a way to access the Source Code of the Unreal Engine Editor to find the code snippet that is responsible for importing assets once you drag them into your Editor window or use the “Import” feature? And would it be able to use parts of that code to create objects at runtime?

I need this specifically for IES profiles which are just text files, but get converted into Texture Light Profiles once you import them into the Engine and I want to be able to dynamically read a string to create such an object in C++ code that I can then call using Blueprints.

Thanks in advance!
