Sunlight doesn't work, meanwhile regular lights work, any help?

[LIPRampage]

Title says it all, i'm creating an onslaught map, i added some lights to some places, and good, they work fine, but... When i tried to place the sunlights and rebuild everything, they don't lit... The map keeps black and dark with 0 sunlight, any help?

EDIT: Noticed the terrain don't lit even before rebuild everything or rebuild only lightning (tried to rebuild geometry and everything, but don't work...) And i took some shots, here they are:

1- No-Lights demonstration, to see the terrain, brushes and static mesh:

2- How was supposed to the sunlight be (it's before rebuild level):

Try setting up a skybox. Well the main thing is you need to add the property 'fake backdrop' to the top surface of your cube. This is where the light, so to speak would be coming from.

Almost worked 100% perfectly... But... It gets only static meshes and terrain, don't lit up brushes...
What now?

PS: Ignore the variety of colors, made that for testing the 6 different sunlight directions.

It should work on bsp. I see in your screenshot that you have selected 'Textured' under your viewport display. Make sure to try it with 'Dynamic Light' selected.
If you meant your static meshes aren't lit, try taking all of the top surfaces of the brush that your map is in, and making them fake backdrop.

Ehm, i know about textured, just took a shot with that setup to show you that there is a brush under the lights, but in the other shots, i'm using only lighting, which should make possible to see the ilumination, but... No sucess at brushes
Ilumination at Static Meshes/Terrain: OK
Ilumination at BSP: Nope.
That's what i meant

EDIT: First pic and last pic are the same place.

I tried a test map to see if the Sunlight would light an area with only bsp. It worked for me, I changed the color, and the color worked as well.
Try to make a test map with nothing else in it to see if you can get that to work. Sometimes eliminating things may reveal the problem.
Also sometimes the Sunlight needs to be angled for it to light up walls, if it is directly facing down, it may light the floor but not light walls at all.
Even if angled it may only light the walls it is pointing at.
If that works, another trick is that if you use more than one sunlight, you can use Special Lit to make it work on only the walls you want it to.
