The lightmapping in Unity is still a real nightmare, I have been baking overnight for 2 weeks now and have yet to get a result without any artifacts at all. Each time there's an object with artifacts and I'll change the settings and scale of that object, check if its not overlapping and leave it overnight to bake, just to find another error. Or a whole bunch that messed up that where alright previously without any reason. (these are all seperate builds). This has basically turned into a sadistic easter egg hunt with my hopes being dashed each time. And a new one I haven't seen before, my whole terrain decided to turn red. Oh the joy. Has anyone found a way to get reliable results from Enlighten/Unity?
