My map is a closed room so the skybox can't be seen. I added lights and the sun volume but when I enter the maps everything is dark but the maps works because when I shoot my gun I can see the flash and the zombies eyes.

I think the sky box has to be closed, as in all of the edges must be touching. I also think that it need to be on very the outside.

Maybe you could show a picture of your map in the radiant editor? Could it be the light is not inside of the box and thus you can't see the light?

You need to add reflection probe(s) to the area.

Try adding a litfog volume thats how I got my lights working sure there are other ways

Maybe you haven´t activated all the lights lightning state, try this, select your light (anything that is illuminating your map), go to the entity info, search for lightning state, then select all the options (lightning state 1,2,3,4), and compile/link/light your map and see what happen.

I had the same problem when spawning to a closed room. If you'll add a model to that you'll see he won't spawn in-game.
I think you need to have some sort of opening like a door or a "hole" in the wall otherwise the game thinks this is an inaccesible area and won't let you do anything inside (as if you got in there by glitching/cheats).

Note: I'm quit new to mod tools so don't take my words for granted.

I fixed the no lights issue but now i need help with another issue 

I get these random white areas in my map:




Idk if it has to do with the reflection probes or what. Also the skybox is completely white when i go outside.
