Very unimpressed so far and thought it'd be worth getting a post up to find out other peoples experiences are. It's a real shame because Enlighten seems great as a real time solution and it looks great in frostbite.
But right now as a baking solution in Unity its very very broken - This is a massive issue for the Unity guys because most people that are using unity are making Mobile games and have no chance of getting games working with real time lighting! We really heavily one the quality of our light bakes to boost the quality of the look of the art work - its a big kick in the teeth when are are unable to produce the quality we saw with Beast in Unity 4.
Guess I'm just curious about how others are finding it, what issues they have and what they are currently doing to work around them. We have now moved onto serious discussions about how we could do our light bakes in Modo or how we can try to hack beast back into Unity 5... We are that desperate.
I'll also share a quick screen grab of front page of the Unity GI sub forum. A lot of people are unhappy - there is a real sense that this tech was added to make a great looking stage demo on a high end PC with very little thought about the end users who's big focus is mobile development.
