More lights on one shader

is it possible to use more than one lightsource within one shader?
spreading the light vector doesn’t work. (without additional scripting the shader?)

the “built-in” shaders of vvvv can only deal with one light source, sorrily.
so you have to write your own shader which repeats all light-source-dependant code for each of your light sources. one idea for this would be to put all of this code into a seperate function within the shader.
so heavy scripting is necessary, yes.

actually its more like copypaste scripting than heavy scripting.
