Thanks, the Lightmap Resolution: 2 does help a lot. I figured the videos were edited for time, but I guess I also wanted to be sure my computer wasn’t the problem.
I’m using the given Room_Start.unity scene in Unity 2019.1.0f2. These are the steps:
- Add a cube.
- Set it to static.
- Add the emissive Red material.
- Check that the Red material’s GI is set to Realtime.
- Turn off Realtime Lighting in the Lighting window.
- When it’s done auto-baking, the red is still illuminating the room.
- Setting Mixed Lighting mode to Baking Indirect makes no difference.
