How do I cause a light_enviornment to cast light at an angle, like it's 3:00 in the afternoon or 10:00 in the morning?

I use a light_spot with Is Sky checked. Make an info_target named Skytarget or something and make the light_spot target it. Now all you need to do is move the target around to play with direction and angle of sunlight.

Oh wait, this is Source. Is it the same thing?

Use a solar calculator.
http://www.srrb.noaa.gov/highlights/sunrise/azel.html

The numbers you need are the Azimuth (for the angle value) and elevation (for the pitch value)
Remember than the angle values in Hammer go counter-clockwise, and the azimuth value the calculator gives you are measured clockwise. You have to convert the value.

For the elevation, you have to put a negative sign before the value, since negative values in Hammer means it points downwards.

For example: if the azimuth value says 60?, you have to put 300? in Hammer. If the elevation is 20?, the pitch has to be -20

Nice... I knew one of those existed, but never bothered to look for it.

Oh wait, I just realized, where do I put this information in? Map Properties? light_enviornment?

The azimuth value is the angle of the light_enviroment and the elevation value is the pitch of the light_enviroment
