hey all, im a beginer mapper and i got a couple of questions about lighting.
1) when i am trying to change the radius of a spot light, what is 1 unit equal to? is it....
A) 1 unit on grid .25
B) 1 unit on grid .5
C) 1 unit on grid 1
D) 1 unit on grid 2
E) 1 unit on grid 4
F) 1 unit on grid 8
G) 1 unit on grid 16
H) 1 unit on grid 32
I) 1 unit on grid 64
J) 1 unit on grid 128
K) 1 unit on grid 256????????

2) How do i change the intensity of the light coming from a spot light? do i......
A) move the spot light closer to the null
B) do something in the entity sub-window
C) something else?

As far as the radius keyvalue, use whole unit incriments. I believe the default radius is 64... so if you want the "spot" of light to be twice as big, make it 128 (it should be a 1 to 1 ratio).

Light intensity, can be from another keyvalue, scale. Again, if you want to double the light amount, type in the key/value scale/2 (if you want to make a dimmer light, you can go scale 0.75, etc.) :)

Also, although I'm not sure if this affects spotlights, adding the key "light" and something more than 300 (the default setting) may help.

Possibly a mix of all three. Or perhaps, if you want a specific spot of light, and alot of "splash" light around it, maybe a couple light entities at that point would be what you need... :)
