hi...! I making a map where there are a pyramide in the middle... And I want to make it dark inside the pyramide , but normal light outside.... ! Can someone plz help me ?
Just use an environment light for the outside and make sure the outer shell of the pyramid is made of world-brushes (non-entities). Anywhere there is an entity will let light thru, unless you use entities that have light blocking properties.
Well I'm assuming you would make the hole at the base and as long as your pyramid has no leaks then the light should only stream in that part. As for making non-entities, it is simply a brush (polygon) before you turn it into an entity.
