UE 4 and 5 Freezes on pasting huge array of vertices

Hey there, i’m trying to paste 40k Vectors in Vector Array in BP but engine just freeze my PC. Is there any other way to paste huge data in Array without using Ctrl+V?

Freezes as in becomes unusable and not responding persistently or freezes for X seconds?


You could try to keep the data in a spreadsheet and import into a data table. The DT can be refreshed from the context menu in the content browser. I had loaded a dictionary with almost 600k entries and it all worked surprisingly well. Updating was not instantaneous but under 10s on a mid-tier machine.
