Hi

Can one have the skycube and the light?
Example:
If I have in my level the skycube, the light does not walk in a room.
If I remove the skycube the light walks well.

Thank you

I've never seen a walking light, but in a game everything is possible. Sky cubes don't affect light. Maybe you placed a wall in your room and put a sky cube texture onto it - then of course the wall blocks light. Put the sky cube texture only on the outer sky box around your level.

One can have the skycube and a place where one needs light as a cellar with a window, of course I puts the sky for the wood that surrounds my level, but nothing, except if I eliminate the sky of my level

Hmm, I'm not sure that I understand what the problem is. Can you post a screenshot of your level in WED, and a screenshot of that cellar window with the light, so that I can see the problem? I'm a little slow-witted, you know.

Maybe talking about sunlight in the closed rooms made?

Or talking about the object that carries the skycube is blocking
dynamic/static lights coming from "outside" the skycube?

Excuse me my friends.
I have creates a new level, a simple room with a window, a skycube and that walks. I very much will like to know why in another level that does not walk any this manner, only I touched on important files as "material.wdl" and other. But nonetheless thank you a lot my friends, because you have me push to revise my case.
Thank you again.

Here a screenshot
