Is there any way to make a map much brighter by messing with the light_enviroment?
In the brightness field there are 4 values:
255 255 255
by default The first 3 are the RGB colour value of the light, the fourth is the brightness value.
See here for suggestions for skyboxes:
And make sure you remember to set the pitch (the default 0 is horizontal and -90 is directly down)
There are 4 nubmers under the light setting, they should be “255 255 255 200” Raise the 200 higher, and there you go, it’s brighter.
