Thanks everyone for the tips. Good to know that it definitely shouldn’t be as slow as it is now.
It also made me think to turn the EDL (Event Driven Loading) back on. I was advised by an Epic staffer to turn that off to get my blueprint Nativization to work, which it did.
But I am now noticing it makes a huge difference to the load times.
Bad news for me if I have to choose between long load times or slow blueprints.
Cheers
