Change directional light color

[Alessandro]

Hello,

 

I need to change directional light color in order to simulate the atmosphere colors in the morning and evening (day/night cycle).

I used the following code, and putted in Update() event in the light self:

 

light_1.light.color = Vec3(myRed, myGreen, myBlue)

 

The problem is, every some seconds, I see in the screen something like a flash white (imagine a lighting in the sky, which enlighten all the environment for a few frames).

 

Is my code correct? Is there any other way to simulate color changing?

 

Thank you for your help!

A light is Vec4, so probably your alpha value gets random values since you use a Vec3.

LOL I will try to use Vec4.

Thank you for the suggestion!
