Why does this material not turn invisible?

Questions & Answers
1

I dragged said material under the var but nothing is working. No errors.

var material : Material;
var bool : boolean;

function Update () {
	if(bool == true){
		material.color.a = 0;
	}
}

The likely reason is that the shader does not support transparency. Try changing the shader for the material to something that you know supports transparency. Try Transparent/Diffuse. Beyond that make sure your import settings bring in a texture with an alpha channel…RGBA 32-bit for example.

Well this is my solution for that. This makes the object disappear(becomes invisible).

I haven’t test this on materials, but it could work.

Hopefully this helps you.

 var object : Object;
    var bool : boolean;
     
    function Update () {
        if(bool == true){
           object.renderer.enabled = false
        }
    }
