Thx for the help from the last question quaker, yea i heard fuzz talking bout the new hammer, bummer we can't use it yet. Now before anyone ask did u search forum, i have, and i've searched the internet too, but everything i found has not helped me. The problem is how do I like a outdoor map. I want a dusky, morning, dawn feel to a snow map. So I placed a light envioment in the map close to the ceiling and the sky, but everytime i run it, it doesn't seem the light works, I don't know how to turn the color down to make it more dark, or add shadows, i assume pitch is for shadows, and the other option is for lighting. Any help would be much appreciated, thx.

on the settings for your light_environment,
pitch is the angle, (-90 is straight down)
so, (someone correct me if im wrong) the horizon would be around -10. But the shadows from that would be quite dramatic.
You can pick the color at the brightness setting. For brightness i would start with a very low setting like 5, and do many bounces. Matching the ambient lighting to your sky of choice always takes a few tweaks.

Yeah, tweaking = good.

Basically more bounces makes for a more diffuse light, less harsh shadows and all that. The colour of the light is determined by the first three numbers, the fourth being the brightness (250 200 200 100 for example; to make it darker lower the last number, to play with the RGB use the first 3). Colour for dawn will likely have some rosy hues, though I don't know what sky you are using. If the sky you are using has an obvious light source (the sun for a daytime map) you will want to align the shadows with it by using the yaw as well as pitch, and the less cloudy and more revealed the source of light is the fewer bounces you want.

If you are running your compile with RAD, and the map is still coming out full bright, you must have a leak. You should check your compile log.
