Niagara Crash When Clicking '+' in Parameter Window

Very easy to reproduce. Simply create a new Niagara System, open it, then hit the ‘+’ button next to ‘Emitter’ on the right-hand side in the ‘parameter’ window. (Bug occurs when you hit any of those items).

Note, this was the FIRST Niagara Asset I created in this project, so no emitters or anything else existed at the time.

Engine will instantly crash in Array.h line 611. The Call-Stack points to SNiagaraParameterMapView.cpp line 479 as the offender.


We’ve recently made a switch to a new bug reporting method using a more structured form. Please visit the link below for more details and report the issue using the new Bug Submission Form. Feel free to continue to use this thread for community discussion around the issue.


Just want to communicate that this has already been fixed. Will be in soon. You can avoid this crash by making sure you selected an emitter track in the sequencer window within the niagara system. Sorry for the inconvenience.
