The emissive lighting will affect realtime Global Illumination. It emits lighting into realtime lightmaps and realtime lightprobes.
The flags are mutually exclusive so if you are using RealtimeEmissive lighting, you must remove the EmissiveIsBlack flag from the material as shown in the example below.
// Remove the EmissiveIsBlack flag from material: MaterialGlobalIlluminationFlags flags = material.globalIlluminationFlags; flags &= ~MaterialGlobalIlluminationFlags.EmissiveIsBlack; material.globalIlluminationFlags = flags;
