Description

The Niagara viewport does not adjust exposure when using the Auto setting for exposure. This is especially pronounced when using physically based values for skylight intensity. 

Steps to Reproduce
  1. Open a Niagara emitter or system
  2. Open Window>Preview Scene Settings
  3. Adjust the Sky Light Intensity in the lighting settings

RESULT

The preview viewport will not adjust its exposure to compensate for the brighter scene. Compare this to the material editor, which will compensate for the change in brightness.
