Unreal Engine - Interior Exterior Lighting Issues

[graemerensburg]

I am using Unreal Engine for Real Time Rendering of a Archviz Exterior/Interior Scene.

 

Please see attached Screenshot.

 

I cannot get the right balance of Interior Exterior lighting. Exterior is too bright, interior too dark.

 

I am using Skylight, Directional Light, No point or Spot lights, Lightmass Portal over Sliding door.

 

I am trying to light the scene as naturally as possible.

 

Auto Exposure is turned off under Project Settings, Renderings.

 

Auto Exposure is turned to Automatic under Lit/Exposure.

 

Post Process Volume Settings - Auto Exposure - Min Brightness 0.5 , Max Brightness 2.0, Exposure Bias - 2.2

 

World Settings - Lightmass Settings

Static lighting Level Scale : 1.0

Num Indirect Lighting bounce: 20

Indirect Lighting Quality : 10

Indirect Lighting Smoothness: 1.0

 

I have left Baselightmass.ini file as I was told because of Lightmass Portals you don't need to change these settings anymore.

 

I have watched so many tutorials but just cannot get the balance right.

 

Any help would be much appreciated.

 

Thanks

Graeme

I'm not an expert but I think you will need to turn auto exposure on when moving from outside to inside if your making a VR. You've got a situation where the outside lighting is too bright for a fixed exposure so it has to be adjusted. If your just rendering out animation then you can set up an interior and exterior camera with different exposure settings.

Activating your copy of windows will help.

 

Devin is correct. You can't have a properly exposed interior camera that will work outdoors. A properly exposed interior camera will always make the outside brighter, and if you take the same camera exposed for an outside shot to your inside, the inside will be pretty dark.
