Ok, I know this is probably going to sound like a simple question, but how would I make a simple sphere shape appear as if its “glowing”?

Thanks in advance to anyone that can help…

Shaders are a bit part of that, but you also need to add a lot (self-illuminated helps to make it glow). A point light, which radiates in all directions, is likely to be what you want.

Here:

```auto
// Glow variables:
private var highlightMultiply = 1.5;
private var originalColor;

function Start () { 
	// get original color for Glow functions
	originalColor = renderer.material.color;   
}

function Glow() { 
	renderer.material.color.r = originalColor.r*highlightMultiply;
	renderer.material.color.g = originalColor.g*highlightMultiply;
	renderer.material.color.b = originalColor.b*highlightMultiply; 
}

function NoGlow() {
	renderer.material.color = originalColor; 
}

```

Now just call Glow() to start it glowing and NoGlow() to reset it!

Woot!
