Light problem

When I compile my map with Mbuilder the lights in the map turn in to a kind of rectangular shape and looks terrible is that just a problem with Mbuilder or am I doing something wrong with my light placement?

Could you maybe post a screenshot? I'm not quite sure what you mean...
If you are unable to upload a screenshot anywhere, you can e-mail it to
jv_map@mods-r-us.net and I'll post it for you, but I can't do that before tomorrow

Thats how i've placed the light in radient. I've got a feeling it should be lower but then some patches of the light go dark.
Thats how it looks after its been compiled in Mbulider. As you can see its all gone a bit of a funny shape.

Sorry, can't see the screenshots. But it may be the video settings you are using in the game.
Point lights should be placed where the bright part does not shine through to the other side of a wall, floor, or ceiling brush. It is ok for the bright part to stick into the wall, just not all the way through. If need be, you can resize them with Key: light and Value: 100 (300 is the default size).
Have you made any other entity settings (key N) for the lights?

i also have a question about light ,what is linear light?how can light be linear?

I think it means the relation between distance from the light and intensity of the light becomes linear (instead of the more realistic inverse square)... hence if you'd move from the light away the 'amount of light' decreases in a lineair way.

Hmm, it obviously doesn't allow remote linking. I'll just put links to them instead.

This is how I placed it in Radient. Is there something wrong with the placement maybe?

thats how it looks when its built in Mbuilder.

those links dont work either...
are you sure you have te full address to the image?
try right clicking, going to properties... and select the WHOLE address to copy.... I use snapfish, and the adresses are like 3 lines, so jsut copying out of the browser wont get you anywhere.

right there'd be an equation like light = x -1
or something
I guess you could have quadratic light
x^2 - x - 1

Well I'd think of something like this (just a guess):
Let:
I: light intensity
r: distance from source
c: some constant defining the light decay
L: the light key as set in radiant
Then:
I =
L -
c *
r
(obviously as long as
I > 0)
Whereas the default equation (non-linear) would be:
I =
L /
r^2
Makes sense?

yeah i guess so

Yes.
Linear, not exact but you get the point
Code: Select all
I R
300 0
250 50
200 100
150 150
100 200
50 250
0 300
Standard:
I R
256 1
128 2
64 4
32 8
16 16
8 32
2 64
1 128
0 256
Very bad example, I
understand it but it's hard to explain...

Linear lights suck, don't use them.

Righto the linear lights are too flat looking, standard gives you a smooth look.

Entity lights suck
Best use surface lights or sunlight
