I’m writing a that imports custom data into a class deriving from UObject. I would like to be able to configure the import via an UI, but it’s not clear how that can be done. My entry-point into the import process is when my implementation of UFactory::FactoryCreateBinary gets called. Are import options supported? Are there any code samples that show how this is done?
Take a look at CSVImportFactory.cpp namely the Construct function, this is an example of creating a UI for import options, also FBX importer has a more complex UI, and I am sure there are other examples.
