Hello...

I know that dynamic lights in game studio are by vertex based... But somebody know if is it possible dynamic lights per pixel based?

Yes, that possible. You need a per pixel lighting shader.

Thanks Zeitwerk... I will search about!
But, Do you have some shader code to pass here?

I'm sorry, I'm not much of a shader guru. ^^ Have a look into the shader forum, there you'll find the right people for that.
