Create a temporary material from a shader source string.
If you have a script which implements a custom special effect, you implement all the graphic setup using shaders & materials. Use this function to create a custom shader & material inside your script. After creating the material, use SetColor, SetTexture, SetFloat, SetVector, SetMatrix to populate the shader property values.
// Creates an additive-blended material and uses it for rendering
var color = Color.white;
function Start () {
var shaderText =
"Shader \"Alpha Additive\" {" +
"Properties { _Color (\"Main Color\", Color) = (1,1,1,0) }" +
"SubShader {" +
" Tags { \"Queue\" = \"Transparent\" }" +
" Pass {" +
" Blend One One ZWrite Off ColorMask RGB" +
" Material { Diffuse [_Color] Ambient [_Color] }" +
" Lighting On" +
" SetTexture [_Dummy] { combine primary double, primary }" +
" }" +
"}" +
"}";
renderer.material = new Material( shaderText );
renderer.material.color = color;
}
NOTE: Creating materials this way supports only simple shaders (fixed function ones). If you need a surface shader, or vertex/pixel shaders, you'll need to create shader asset in the editor and use that.

Create a temporary Material from a Shader.
If you have a script which implements a custom special effect, you implement all the graphic setup using shaders & materials. Use this function to create a custom shader & material inside your script. After creating the material, use SetColor, SetTexture, SetFloat, SetVector, SetMatrix to populate the shader property values.
// Creates a material from shader&texture references
var shader : Shader;
var texture : Texture;
var color : Color;
function Start () {
renderer.material = new Material (shader);
renderer.material.mainTexture = texture;
renderer.material.color = color;
}
// Creates a cube and assigns a material with a builtin Specular shader.
function Start () {
var cube = GameObject.CreatePrimitive (PrimitiveType.Cube);
cube.renderer.material = new Material (Shader.Find("Specular"));
}
Create a temporary Material by copying the shader and all properties from the source Material.
