Developer Notes

The event driven loader is unavailable in binary engine distributions. Only source code distributions can use it. A warning message about it is logged to the output window when attempting to enable it in non source code distribution.


The Event Driven Loader checkbox is unchecked (false) by default, however attempting to click it does not set it to checked (true). Attempting to set s.EventDrivenLoaderEnabled=True in the DefaultEngine.ini file reverts to False when the project is opened.

Steps to Reproduce
  1. Open UE4 Editor (any project)
  2. Navigate to Edit->Project Settings->Engine->Streaming
  3. Click checkbox for Event Driven Loader Enabled

Checkbox remains unchecked / disabled

Setting switched between false/true when the checkbox is clicked.
