Steps to Reproduce
  1. Open the project attached.
  2. It's a simple and reasonable setup:
    Niagara emitter samples static mesh surface for spawn location
    Source Mode (in Sample Static Mesh module) is set to Attach Parent
    And the Niagara component is attached to the static mesh actor with a scale of (1.0, 1.0, 0.3)
  3. This only happens to GPUSim

 

Problem:
Output Log would throw error when we open the level for the first time
Although the Niagara system works regardless the error
