    Here is a better screenshot showing four of the problem probes. They are part of a prefab, but in another scene the same probes work in the prefab.

    Ok so, why do my probes think they receive red light?
    I have tried everything

    Found the bug. Atleast one probe has to be exposed to directional light. Is this bug known?

    We are ready to record our Steam Greenlight video and this is one of two things that stop us from doing that so it would be super if someone from Unity please could give ut some attention

    This is how it affects dynamic objects in game

    We also have some cases were its not 100% sure the probe is faulty, they look like this

    They make the dynamic objects lit up very uneven, like black on someparts while superbright on others. I will see if I can get a screenshot of this, until then you can see in our first official gameplay footage that the ligthing on dynamic objects are a bit uneven and off.

    Yep, I've run into a couple of things like this
    For me the cause of the "X" pattern was a bug caused by scenes containing area lights having *other lights* not contained within a probe volume... so got any area lights in your scene?

    If that's not the case...

    I've been dealing with a visually similar super-bright-colour bug today, and narrowed it down to multi-scene situations where my manager scene had bizarre lighting data baked into it that was not being correctly cleared affecting other scenes... so if you've got a multi-scene set-up, try closing Unity, deleting their lighting data folders, and baking again with only lit scenes open.

    But it's pretty likely your thing is a different problem entirely, the new light probes seem pretty buggy, so hopefully Unity can help you out soon!

    Hi there, we have a directional light and two indoor parts on this scene with some point lights. I have tried both clearing the Gi cache and delete the baking data from the scene and rebake. Nothing helps. This is the only baked scene we have sofar i the game.

    Hi, we are aware of this bug and we are working with Geomerics to get a fix into the next Enlighten build.
