Entity is bright... just one side

Well, I have an annoying problem, here.

I have a door built as a map entity. The problem is that one side is too bright.

I try the most common issus and I can say:
1. The door is not interscting any block
2. The lights in entity are the same as the level.

Here is one side of the door.
Here is the "bright" side of the same door.

How can I fix this?

Thanks!

was there a sun in the level when you compiled the door?

I noticed this too. One side of map entities are lit by the sun even though I set the sun to pitch black. Couldn't figure it out, so I just set the sun elevation to 90 degrees where it will be least noticed as a temporary solution.
...would be nice if someone has a better solution tho.
