// Caution: C# code in BaseLitUI.cs call LightmapEmissionFlagsProperty() which assume that there is an existing "_EmissionColor"
// value that exist to identify if the GI emission need to be enabled.
// In our case we don't use such a mechanism but need to keep the code quiet. We declare the value and always enable it.
// TODO: Fix the code in legacy unity so we can customize the behavior for GI
