Objects goes Dark in Unity 5.6.0f3

[Too-Nerd-To-Die]

Hello, I’m having a problem in the new unity, I do not know if it’s a new configuration that was missing or if it’s really a bug, I was using Unity 5.6.0b6, and I did a fast blocking working with some primitive cubes , In the scenario there is nothing special, only the new postprocessing effect, but if you turn it off the problem continues.
In the Unity version 5.6.0f3, with the same settings, I just imported the project and pressed play in the scene and the objects becomes dark, the two setups are not baked, what could it be?

When you open the lighting panel, are you seeing any errors regarding the Lighting being built with an older version of Enlighten (invalid)? I’ve seen issues where a re-light / bake of the scene(s) are required. There’s also the new lighting modes to take into account with Unity 5.6.
