How to not save a variable but have it persist when PIE?

Development Programming & Scripting

I have an array variable, contains a huge precomputed data. Saving it (not save game, but in editor with the map) fail because it’s more than 2GB in size. I tried NonPIEDuplicateTransient hoping that the data don’t get saved, but get duplicated during PIE, so we can skip the precomputation part which is very time consuming. But even with NonPIEDuplicateTransient, the data is still saved, and because it’s over 2GB, saving just crash the editor.

So, reiterating the question, is there a way ?

Thank you!
