Tom,
Not is it.
Acttually i want make a light effect into a dark room based in a external light (in another words, a light from external to internal enviroment).
These work for me............ play with all the angles and then try some of your own. Positive and negatives apply here also........
With the light selected, hit "n" to bring up the entity inspector
first number ( angles ) is the "key" ... second number is the "value" 90 90
first box type angles....... the numbers below go in the value box. After typing these in, hit enter to make them apply themselves.
try these ( all in the value box )
90 90
45 0
22.5 -90.00
45 90
45 270
45 180
45 135
45 315
you can use a negative ( - ) where you want. Each number you type changes the angle at which the light will more or less focus it's direction. You can use any odd number you can think of. The light will "focus" accordingly.
If you need to make a focused beam. think I saw a tut on this site somewhere.
