gridsize is the resolution of the light grid. The ligth grid is used to light moving models, mostly players. AFAIK, the lightgrid is always a rectangular block, defined by the extents of your level, or a brush with the lightgrid shader on it. There is a limit to the amount of light grid data that can be in a .bsp file (8MB if I remember right.) So if your map is too big, you need a lower resolution light grid. q3map2 should do this for you automatically, so there is actually no reason to set it.

_minvertexlight sets the minimum light value of a vertex lit surface. I assume _mingridlight does the same thing, but for the lightgrid. There is also _minlight, which sets the minimum value for lightmapped surfaces. This is sort of light ambient, but not quite.

No, you don't need to use any of them. They are for fine tuning various aspects of your lighting.
 

Ok, when u connect the two entities you are forming a spotlight, so you have two options to light the model.

- use another light entity close to the model
- place a brush inside textured with a light shader.

Light Styles, by UlT1MaT3


Thanks to UlT1MaT3 for the work put into this tutorial.


In this tutorial you will learn how to make fire like candles burn and give off light, a light to flicker, and to make a Strobe light!


Open your map you have already made if not make a room with four walls and a ground and roof. now first if you want to make fire flickering you must find a fire texture maybe your own.


Now you must select your light and press "n" and then in "key" style the style of appearance the light gives off. now in "value" 3 which is the candle! and now you will have a candle type light which should flicker like fire, and here is how to do the rest of these lights


"style" 0 Normal
"style" 1 FLICKER (first variety)
"style" 2 SLOW STRONG PULSE (BRIGHT)
"style" 3 Candle (first variety)
"style" 4 Fast Strobe (strobe Light)
"style" 5 Gentle Pulse 1
"style" 6 Flicker (second Variety)
"style" 7 CANDLE (second variety)
"style" 8 CANDLE (third variety)
"style" 9 SLOW STROBE (fourth variety)
"style" 10 FLUORESCENT FLICKER
"style" 11 SLOW PULSE NOT FADE TO BLACK
"style" 12 FAST PULSE
"style" 13 Test Blending


and to add colors to your light select your light and then press "k" which will if you want to flicker put "key" style "Value" 6 and then you should have your color value and say red then your red light will flicker!


Part 2


You want to beable to make your light position o­n a certain spot of your map, so first you must press "n" to open entities window and then find light and put in "key" target - the targetname of the info_null the light is pointing to "value" l1


and then find the section you want to add the light, so now select what else you want it and then press "n" o­n the section you want the light to shine o­n and then put in "key" targetname and in "value" l1 and then you


hope this helps!
 

when making the pk3file... dont forget the <mapname> folder from maps with the lm_ ... pics in it... as well as the q3map2_<mapname>.shader from the scripts folder. when changing the mapname afterwards, besides .bsp, levelshot, minimap, arenafile-name and the stuff inside the arenafile, you also have to rename the q3map2_<mapname>.shader shader, as well as ALL mapnames within it. can easily be a dozen entries.
every <old mapname> and old path has to be changed!
