Well I am trying to bake a fairly large scene with terrain in 2017.4.30f1 and after many hours of computation I figured something must be set incorrectly so I cancelled the bake. After the bake my objects and terrain have an overexposed look and are super bright. I tried clearing the bake light data and reloading the scene… that did not fix it. Did I just f’ this up permanently?
What your environment and light settings?
