Repro:

- Download and import the attached repro project
- Open the Scene SampleScene.unity
- Select the light Spotlight
- Ensure that the mode is set to Mixed
- From the Lighting window, ensure that Realtime GI is selected
- Generate Lighting
- Observe the lack of Indirect
- Change the Light mode to "Realtime"

Observe:

When the mode is Mixed, there is a warning in the UI that states, "Light mode is currently overridden. Enable Baked Global Illumination to use Mixed or Baked light mode". This implies that the light should be behaving as "Realtime". However, there is no indirect lighting. Changing the Light mode to Realtime, it is clear what the effect should be.

Expected:

As described in the warning, Mixed mode lights should behave as realtime lights. Realtime lights propagate lighting through the Enlighten solution. That Mixed mode lights do not do this - I believe - is therefore unexpected behaviour..
