Since yesterday I have been struggling with emissive lights and GI on latest beta of Unity and a Lightweight render pipeline. It seems to be behaving very inconsistently. Sometimes the lights are being baked and sometimes they are completely ignored. Ticking the baked global illumination on and off seems to help sometimes. Unity Version: 2018.3b10 Lightweight Render Pipeline: 4.1.0-preview If there is an interest I will do more tests with different Unity - Renderer combinations. The screenshots are made exactly the same way. Only thing I did was tick the baked GI toggle. I just noticed there was an update... 4.2.0-preview works fine!
