    Hi! I was trying to light up a scene and well, it didn't. The odd thing is that in the game view the game is almost dark but on the indirect light view of the scene, the whole scene is illumineted. Does anyone know what the problem could be? LightIndirectView.png LightShadedView.png

    Hello! I can think of the following culprits:
    • You have aggressive auto exposure settings. Try disabling auto exposure, and see if that helps.
    • Materials with a high smoothness and metallic value will not contribute to GI. Make sure that your scene contains diffuse surfaces from which light rays can bounce and scatter. Alternatively, you could write a custom meta pass shader: https://docs.unity3d.com/Manual/MetaPass.html
