Garry’s Mod is a sandbox mod for the Source Engine. Unlike normal games there aren't any predefined aims or goals. Players are given tools and are left to entertain themselves. The player is in a world where objects can be created and destroyed on demand. Where people can be created and destroyed with the click of a mouse. A world made for him. A world he made.
Derp derp derp.
OH, i thought it said lightning practice! I was like, what? there ain't no lightning here!
You're not looking hard enough my good sir :)
He means the lightning of the picture,I don't understand very well but I believe it has to do with the map or model or both.(no wait,I know where is but forgot what it is)
It's just a random picture,more like for tests from one of our excellent Gmod posers here: Ninja_Nub.
To be exact, a picture with poor lighting is this.

One with good is this one.

Lighting is a bit like photography.
You set up lamps and make the pic be more like a photo study instead of a usual pose.
Just the info I needed.
