I have an example map called "simple sunlight" where I have a window with a "skybox" that contains a light_spot in it, with it targeted to an info_target inside the room. Once you look at this example map, and notice the comments under it, you'll see what was suggested.
For some reason the one suggestion isn't working...
Here is the original screenie with the "box"
Here is a screen shot of the new configuration...
And here is the "side" view in hammer of that configuration...
If anyone can shed some "light" on this problem you know I'd be appreciative, as this is my first example map ever and I refuse to give up on such a simple problem hehe.
