How to make a bright sun

I need a sun that will light the entire map. light_environment dosent work, it only lights the map a small amount.

Did you adjust the brightness? The first 3 values are RGB, the last is the brightness.

How bright does it need to be? Ive set it up to 100 and its still to dim to play.

Set it to like 800

100 is usually the brightness needed in the ambient setting, try setting the brightness in the main setting to somewhere between 800 - 1000.

This list might be useful for deciding on values to use for different skyboxes too:

OK thanks, ive figured it out. Ive gotten a good enough lighting.
