Question by leandroreschke · Jul 20, 2017 at 07:42 PM · materiallightglobal illuminationemissive

Emissive realtime light not working on Unity 2017.1?

I tested with a full static cube, he has a emissive material, the light bakes into static meshs with poor resolution, but with moving objects it's not working, i already set it to realtime in the material tab and GI is both baked and realtime activated. Could someone help me?

Maybe you just need to generate new lightmaps, and its not set to auto? im having similar issues with very strange / poor resolution lightmaps. See screenshotalt text

everything else in my scene is lit fine. Just the floor is acting strange.

Have you ever managed to fix this? We are having weird problems with emissive light on Unity 2017.3.0. The baked scene has some weird white/yellow light spots in random places, this wasn't happening in Unity 5.6.2. Yet when I choose to view the "Baked Emissive" maps from the Object $$anonymous$$aps, it says they are not available.

If you want to get it working with moving (i.e. dynamic) objects, you need to write some scripts to update the GI. I've written an article sometime back about getting emission lighting to work properly in Unity -- it covers the scripts that you need to get realtime emissives working too: https://blog.terresquall.com/2020/01/getting-your-emission-maps-to-work-in-unity/
