Summary

All custom Niagara do not cook when we launch the game. The error says “missing an effect type asset” but there is an effect type already there, only one default effect type that we can not change. Default unmodified Niagara works, but when you customise it it fails to cook.

Steps to Reproduce

  1. Place a Niagara all works fine
  2. Place a Niagara and make any change and fails to cook
  3. The game will start launching, but while loading says “missing an effect type asset”

Expected Result

Expected the game to launch. It worked last update without issues we made no changes since.

Observed Result

“missing an effect type asset”
