Ok so what I'm trying to do is change the brightness of a material by changing it's "V" value in the Tint Color property. Not sure where to go from there though. This what I've got so far:

// The Material to change
var SkyboxMaterial : Material;

function Start () {
     // Set the initial tint
     SkyboxMaterial.shader.GetComponent("TintColor");
}

I'm trying to do this so I can Mathf.SmoothDamp my skybox from black to the blue color that it normally is. Any help would be appreciated.
