+h1. Lighting
+
+In netradiant, there are two kinds of lights, real time lights (which must be added in-game) and radiosity-based lights (which are added in radiant). This article will deal with both.
+
+h2. Real time lights (rtlights)
+
+Real time lights are added and modified using the following console commands, accessible in-game using r_editlights_help.
+
+|_.Command|_.Function|
+|\2=.Settings|
+|r_editlights|enable/disable editing mode|
+|r_editlights_cursordistance|maximum distance of cursor from eye|
+|r_editlights_cursorpushback|push back cursor this far from surface|
+|r_editlights_cursorpushoff|push cursor off surface this far|
+|r_editlights_cursorgrid |snap cursor to grid of this size
+|r_editlights_quakelightsizescale |imported quake light entity size scaling 
+|\2=.Commands|
+|r_editlights_help |this help|
+|r_editlights_clear |remove all lights|
+|r_editlights_reload |reload .rtlights, .lights file, or entities|
+|r_editlights_save |save to .rtlights file|
+|r_editlights_spawn |create a light with default settings|
+|r_editlights_edit command |edit selected light - more documentation below|
+|r_editlights_remove |remove selected light|

+|\2.=Edit commands (given as arguments to r_editlights_edit|
+|origin x y z |set light location|
+|originx x|set x component of light location|
+|originy y|set y component of light location|
+|originz z|set z component of light location|
+|move x y z |adjust light location|
+|movex x|adjust x component of light location|
+|movey y|adjust y component of light location|

+|anglesx x|set x component of light angles|
+|anglesy y|set y component of light angles|
+|anglesz z|set z component of light angles|
+|color r g b |set color of light (can be brighter than 1 1 1)|
+|radius radius |set radius (size) of light|
+|colorscale grey |multiply color of light (1 does nothing)|

+|normalmode 1/0 |turn on/off rendering of this light in rtworld 0 mode|
+|realtimemode 1/0 |turn on/off rendering of this light in rtworld 1 mode|
+|<nothing> |print light properties to console|
+
+The most important commands to remember are r_editlights, r_editlights_edit (color, realtimemode and radius arguments), and of course, r_editlights_save. You will not see your light and its effects in real time if you do not execute r_editlights_realtimemode 1 while having selected the light.
