I just tried changing my LightRange light,far# value, and nothing appears to happen.
Is this becuse the default light (light=CreateLight() or light=CreateLight(1)) has an infinite range, unlike CreateLight(2) and CreateLight(3)?
Yes light type 1 is directional and has infinite range.
Your lighting may be maxed out, in which case turn off any lights of type 1 and you should be able to see the effect of any type 2/3 lights then.
Thanks Shambler.
No, I just want a simple 'sun'.
Do I still have to 'PointEntity light' down to my terrain, or is that light omnidirectional?
A light of type 2 has a position but no direction, it's like a lightbulb.
[edit] it creates light that shines in all directions.
If you want a sun then that is what light type 1 is for, unless you want it to fade out that is.
