Gl skyboxdist

Name: gl_skyboxdist
Default value: "2300"
Flags:

Distance to position the skybox at. It's possible range depends on the value of gl_maxdist. 2300 is the default, which goes with a gl_maxdist of 4096.
Note that if gl_maxdist is set to 0, the view is rendered with infinate depth, in which case you can put something stupidly huge into gl_skyboxdist without issues.
