I have a D3D Application which generates lightmaps, but i got a problem. when to lights(point) comes close and the radius is intersected i just add the values togheter, but i then get some strange artifacts.Maybe there is a better way of doing this? ofcourse i''m checking if the result gets over 1.0 then i''m setting it to 1.0. if i have a green light combined with a pink light i get a different result from combining a pink light with a green light.

I think to get the right color, you shouldn''t add, you should take the average.
Newbie programmers think programming is hard.Amature programmers think programming is easy.Professional programmers know programming is hard.

You should add. But dont forget to clamp to 255(or 1.0f) in the end.

What do you mean with Clamp?

It means that if the result of your adds exceeds 1.0, you should set the result to 1.0.
