Looking to use bluprints as a base class with overiden funtions without spawning it.

[PREDALIEN]

You can get the CDO for any Blueprint using:

BlueprintAsset->GeneratedClass->GetDefaultObject()

@Doc.gdi

only exception are function libraries

CDO is also created for libraries. Blueprints call functions in it.

@Doc.gdi

in c++ is possible

Yes, C++ has static functions that can be called without creating an instance using:

ClassName::FunctionName()

But they have some limitations.
