light grid, reflection probe and lights are in place, still this happens, any help please.

This can happen if you use too big brushes. You can prevent it by using terrain-patches which will also make it easier to bring in a bit more detail.

He hasnt got any big brushes in his map (Hes around my house) Hahaha! But yeah its just normal flat brushes. My maps work fine but his just has lighting problems like this

still happening, something to do with lights

Make a really big brush using the caulk texture. The brush should surround the entire map. Hollow the brush so you now have a really big box around the map. Give the inside faces of the box any sky texture. It doesn't matter if it matches your skybox model as it will draw invisible but it is good practice to choose one that matches as closely as possible.

I suggest the two of you find some tutorials on making terrain patches. Just normal flat brushes should not be used in place of terrain as they are just completely flat and look bad. https://www.youtube.com/user/BlackJackJonnyy/videos has some good ones.

thanks another thing is i can hear the main enu theme in-game ? :S
