Regression

No

Realtime direct contribution is missing when using mixed lights in subtractive lighting mode

Global Illumination

-

How to reproduce:

1. Open the attached project ("MixedLightBug")
2. Click on Directional Light in Hierarchy
3. Change the Shadow Type to Soft Shadows

Notes:

Expected result: realtime direct specular is visible on the sphere
Actual result: direct lighting is baked into the sphere

Reproducible with: 2017.4.29f1, 2018.4.2f1, 2019.1.7f1, 2019.2.0b6, 2019.3.0a6

- Affects all lights (point, spot, and directional)

    Resolution Note (fix version 2019.3):

    By design : No shadow casting mixed lights in substractive or shadowmask fallback to realtime lights.

    Details:
    mixed mode (substractive and shadowmask) make no sense for no shadow casting light as the whole point of these mode is to handle shadowing. Thus those lights need to fallback to either fully baked or realtime.

    As specular have a huge quality impact on final rendering and realtime lights without shadow are not very expensive it was decided that this would be the fallback. However one can still force the light to be a fully baked light without shadow by selecting this mode explicitely.
